The iPhone 4S is a touchscreen slate smartphone developed by Apple Inc. It is the fifth generation of the iPhone, a device that combines a 3.5 inch (89 mm) touchscreen iPod, mobile phone, and internet client. It retains the exterior design of its predecessor, the iPhone 4, but is host to a range of improved hardware specifications and software updates compared to the previous model. Integrated software and hardware changes support the introduction of new user interface and functions by Apple. Highlights include a voice recognizing and talking assistant called Siri, personal computer independence, cloud-sourced data (iCloud) and an improved camera system. A selection of the device's functions can be controlled by voice.
The iPhone 4S was unveiled at Apple's "Let's Talk iPhone" event on October 4, 2011 in Cupertino, California. Apple started taking pre-orders for the iPhone 4S on October 7, 2011 in seven initial countries (United States, Canada, Australia, United Kingdom, France, Germany, and Japan) with a first delivery date set for October 14, 2011, and available on that same day for direct store sales in those countries. It was released in 22 more European, American and Asian countries, including Ireland, Mexico and Singapore on October 28.
It will be available on 100 carriers in 70 countries overall, including AT&T, Verizon, and for the first time, also for Sprint and C Spire customers in the United States. In Japan, it is available for au (a KDDI brand) and Okinawa Cellular, for the first time.
For US customers, while pre-orders for purchasers buying contracts started on October 7, 2011, unlocked (contract-free) sales started on November 11, 2011.AP said that AT&T described early iPhone 4S demand as "extraordinary".

History

Announcement

For some, a series of expectations about Apple's next generation phone, including various specifications and a predicted name ("iPhone 5"), were built up in the time preceding its debut.After the iPhone 4S was announced, there was some disappointment about the new phone's name. However, as early as May 2011, some leaks had a fairly accurate description of the product including the name "iPhone 4S", the A5 chip, HSDPA, new/better camera, and Sprint carrying.As it turned out, there were no external differences between the iPhone 4 and iPhone 4S; all of changes were internal. Nevertheless, it has still been described as a "dramatic leap forward in technological innovation and sophistication...". The keynote was the first in which Tim Cook led since the Verizon keynote earlier in the year. It was also Cook's first product launch without Apple co-founder, Steve Jobs, whose health was deteriorating and who died the day after the announcement of iPhone 4S. Tim Carmody of Wired praised Cook for focusing on company achievements, calling him a "global business thinker" and a "taskmaster". One unique aspect was that the whole management team of several people took turns discussing the new products.

Reception

Initial reaction to the iPhone 4S announcement was generally favorable. Echoing technology pundits, Reuters suggested that the lack of a more radical departure from the iPhone 4 could open new market opportunities for rivals. Shares of Samsung Electronics, HTC and Nokia gained on Wednesday after the 4S was announced, while Apple stock dipped sharply. However, later in the day Apple shares rebounded, ending at a 1% gain. Analyst C. K. Lu of Gartner believed that Apple no longer had the leading edge and 4S would only sell due to brand loyalty, as fans had been expecting an iPhone 5 with a thinner profile, bigger screen, and stronger features.Some of these same people had also wanted a cheaper, stripped-down iPhone 4.
The German phone company Deutsche Telekom said they were "satisfied" with consumer interest.
With the launch of the pre-order, AT&T said that the demand for the iPhone 4S was "extraordinary". Over 200,000 pre-orders were placed within 12 hours through AT&T. In addition, AT&T, Verizon, and Sprint sold out of pre-order stock by October 8th, 2011 and by the 9th there was a 1-2 week estimate on new pre-orders to be filled. On October 20, 2011 AT&T surpassed 1 million iPhone 4S activations.
On October 10th, Apple announced that over one million iPhone 4Ss had been pre-ordered within the first 24 hours of it being on sale, beating the 600,000 device record set by the iPhone 4.The 16-month wait between the iPhone 4 and the iPhone 4S may have contributed to overwhelming sales as well.
By October 11th, early reviews of the iPhone 4S were released. Reviewers noted the software voice assistant, camera system, and processing speeds as significant advantages over the previous model.
Retrevo surveyed more than 1,300 U.S. consumers and reported that 71 percent of all smartphone owners were not disappointed by the new iPhone 4S but 47 percent or almost a half of current iPhone 4 owners were. 12 percent were hoping for a bigger display, 21 percent wanted a refreshed design, and 29 percent desired 4G.
Unlike previous iPhone models, the sales of the iPhone 4 had not climaxed prior to the 4S introduction.For example, the 3G model came out when sales of the first iPhone had declined to less than half their peak.In addition, iPhone 4 users had high marks for being satisfied with their phone.Nevertheless, they wanted even more from Apple, but forgot that from Apple's perspective the iPhone 4 was still a hit and that new users may not be bothered by the look and feel staying the same, because they did not have iPhone 4 in the first place.^[
On October 17, 2011, Apple had announced that four million iPhone 4Ses were sold in the first three days of release, and 25 million iOS users had upgraded to the version supported by the iPhone 4S, iOS 5. Phil Schiller, Apple’s senior vice president of Worldwide Product Marketing, stated that the “iPhone 4S is off to a great start with more than four million sold in its first weekend—the most ever for a phone and more than double the iPhone 4 launch during its first three days.”
On October 19, 2011, private wireless carrier C Spire Wireless announced they will be beginning selling the 4S as well in the United States. It is the smallest provider to carry the 4S so far as well as the first privately-held carrier.
Design

The iPhone 4S is primarily a combination of a hand-held computer, cell-phone, GPS, digital/video camera, and music player into one device, powered by a rechargeable 1432mAh lithium-polymer battery. It is supported by an online infrastructure where media and secondary applications can be acquired to run on the device, thereby expanding its capabilities.
The iPhone 4S retains almost all of the same design features as its predecessor, the iPhone 4. The front and back are both flat, the screen being made of glass. There is a camera on the back and the sides are stainless steel with metal buttons. It keeps the 3.5 inch (8.89 cm) screen of past iPhones with the "home" button at the bottom. The iPhone 4S comes in two colors, black and white.

Hardware

Antenna

Comparison between iPhone 4 hardware (top) and iPhone 4S hardware (bottom). Notice the repositioned antennae (the visible stainless steel which forms the perimeter around the phone).

Improving on the external stainless steel, dual-antenna design of its predecessor, the iPhone 4, Apple has redesigned the antenna in the iPhone 4S so that the cellular radio in the phone can choose between two antennas, depending on which is sending or receiving signal best. These two antennas are part of the stainless steel band that wraps around the sides of the iPhone 4 and the iPhone 4S. The bands on the iPhone 4 are divided into four antennas, cellular, Bluetooth, GPS, and Wi-Fi, while the iPhone 4S, in addition to the iPhone 4, has the cellular (GSM) antenna divided into two pieces. Therefore, if the iPhone 4S is gripped in such a way as to attenuate one piece of the cellular antenna, the radio will switch to the other piece that isn’t being gripped, thereby correcting the flawed antenna that plagues the iPhone 4.
The iPhone 4S is theoretically capable of supporting a maximum throughput of up to 14.4 Mbps with HSDPA as a result of an upgraded radio chip inside the phone, in addition to being a world phone, so both CDMA and GSM customers can roam internationally on GSM networks.It also supports Bluetooth 4.0.

Camera

The iPhone 4S features an 8 megapixel camera and 1080p video recording.

The camera on the iPhone 4S is capable of shooting 8MP stills (3264 by 2448 pixels) and recording 1080p videos at thirty frames per second with upgraded quality (30% better clarity, 26% better white balance, color accuracy) due to an additional lens, IR filter, a wider f/2.4 aperture, and Image signal processor (built-in A5)The camera can now be accessed directly from the lock screen, and the volume up button as a shutter trigger. The built-in gyroscope is able to stabilize the camera while recording video. Other features of the camera are macro (for close up pictures) and faster capture including being able to take its first picture in 1.1 seconds and the next half a second later.

Input and output (I/O)

Like the iPhone 4 the 3.5 inch 960 by 640 pixel Retina Display supports multitouch, a technology that allows multiple simultaneous touch inputs. Siri, a voice control feature exclusive to the iPhone 4S, interprets voice commands and can give visual and auditory feedback. The iPhone 4S has two volume buttons and a vibrate on/off switch on the left side. On the top left there is a 3.5 mm Headphone jack and the lock/power button is situated on the top right edge of the device.. The right side of the device is devoid of inputs except for a SIM card slot. The bottom of the device features a speaker output on the right and a microphone input on the left with Apple's proprietary 30-pin dock connector in the center. The top left on the back of the device houses an 8 megapixel f/2.4 aperture camera with an LED flash.
The iPhone 4S supports video out via AirPlay and various Apple A/V cables. Supported video formats include such as H.264 (1080p 30 fps max.), MPEG-4 video, and motion JPEG (M-JPEG).
In addition to user inputs, the device also has several other sensors, such as a 3-axis gyroscope that allows it to detect its orientation.

Power and battery
The iPhone 4S is stated to have 200 hours standby time (iPhone 4 300 hours), 8 hours talk time on 3G (iPhone 4-7 hours), 14 hours talk time on 2G, 6 hours 3G browsing, and 9 hours Wi-Fi browsing.However there are widely reported issues of rapidly decreasing battery level. The time of use depends on power from the lithium-ion polymer battery inside the device. It can be recharged by power from a USB port or power adapter. The battery is enclosed inside the device and is designed to be removed only by technical experts.

Processor, memory, and storage

Further information: Apple A5

The iPhone 4S has a dual-core Apple A5 processor,compared to the single core Apple A4 processor used in the iPhone 4. It has 512 MB of RAM, the same as its predecessor.Maximum available storage size increased to 64 GB whilst the 32 GB and 16 GB model options were retained. The screen is the same as the previous generation iPhones; 3.5 inch, 640×960 resolution (Apple's "retina" design). The improvement in interactive multimedia applications was obvious compared to its predecessor. However, applications that take more advantage of the new specs will take time to be developed and released. In one early review it scored 677 in a Geekbench benchmark speedtest compared to 380 for the iPhone 4, higher being better.

Features

The iPhone 4S is the first iPhone that does not have to be connected to a computer in order to be activated on its initial software. Shown is the iPhone 4S's setup screen.

Gaming

Siri

Main article: Siri

The iPhone 4S introduced a new automated voice control system called "Siri", unique to the 4S,that allows the user to give the iPhone commands, which it can execute and respond to. For example, iPhone commands such as "What is the weather going to be like?" will generate a response such as "The weather is to be cloudy and rainy and drop to 54 degrees today". These commands can vary greatly and control almost every section of the phone. The commands given do not have to be specific and can be used with natural language. Siri can be accessed by holding down the home button for an extra amount of time (compared to using the regular function). An impact of Siri, as pointed out by Apple video messages, is that it is much easier and/or possible for people to use device functions while driving, exercising, or when they have their hands full. It also means people with trouble reading, seeing, or typing can access the phone more easily.
Its not clear what the impact of Siri speaking in public will be, but it does not have to speak out loud and can be used with headphones. One interface feature of Siri is that it can be activated by holding the phone to a person's head. The iPhone 4S has a proximity sensor.
At launch Siri supports French, English, and German languages.In one early review, German Siri handled the language well but needed more information from supporting databases, such as route information and possibly the Wolfram Alpha "Computational Knowledge Engine".One early review noted its good performance in English, although it did confuse "4" and "for" at one point. The New York Times said Siri's ability to comprehend was "mind-blowing".
The Harvard Business School described Siri as the new phone's most interesting feature, and how well it works could make or break it. Apple says the A5 is a reason why Siri may not come to other devices even with iOS 5 upgrades. However, some gadget reviewers believes otherwise. Several smartphone reviewing sites have pointed out that Apple is making Siri exclusive to the iPhone 4S because that is the only selling point of the phone compared to the previous iPhone 4.
Siri is supported by the A5 chip and currently an iPhone 4S exclusive.Siri also needs internet access to function. When used for the first time, Siri does not require setup but does adapt to a user's voice over time, and can also be taught certain things directly. A number of aspects of the software can be configured, such as language and its voice feedback ability (its ability to talk back).
At launch Apple said Siri is still in Beta, and it has a certain set of abilities with restrictions, such as being able to dictate texts but not emails, and only controlling certain apps. Nevertheless one area it may be useful is driving and exercise activities. It is integrated with Apple's Find My Friends program (which debuted at the same time as the 4S), so Siri can potentially answer questions like "Where is my wife?"When it is enabled, Apple's Find My Friends lets a social group know where each other are and Siri can use this information to answer questions. Siri can be taught information, so it knows who a person is referring to when they use generic terminology on that device.
Recently iPhone 4S users reported that there is a security Loophole in iPhone's Siri which allows unauthorized users to bypass the passcode lock to perform tasks like making calls and sending messages with the help of Siri. However, this loophole can be dissolved simply by changing settings on the iPhone 4S.
The British English voice for Siri is provided by Jon Briggs.

Messaging

Main article: iMessage

On the iPhone 4S, texting can be done aided by the voice assistant which allows speech-to-text.In addition to regular texting, messaging on the iPhone 4S is supported by iMessage, a specialized instant messaging program and service that allows unlimited texting to other Apple iOS 5 products. This supports the inclusion of media in text messages, integration with the device's voice controlled software assistant, and read receipts for sent messages. iMessages are in blue, and regular texts in green in the screen bubbles.Input to the computer comes from a keyboard displayed on the multi-touch screen or by voice-to text by speaking into the microphone. Entered text is supported by predictive and suggestion software as well as a spell checker, that includes many regional dialects like Swiss spoken French.
Since Siri can send text messages, a person can text and drive without taking their eyes off the road, as shown in Apple's video ad.Another example, is that a person can ask Siri for information while they are cooking and their hands are messy.It also makes it much easier for people with physical disabilities such as blindness to compose and send text messages.

Language

At announcement plans were in place for the iPhone 4S to support many languages from around the world. Different features have different language requirements, such as keyboards compared to the word predictor and spell-checker, which needs a large dictionary of words. Language support is related to the iOS 5 operating system that the device launched with, although not always. The Siri digital assistant supported French, English, and German at launch. Since it uses a software based keyboard supported by the multi-touch display, it can support many different keyboard layouts without having to change physically. The iPhone 4S can display different languages and scripts at the same time.

Network

The device is a World phone and can work on both GSM & CDMA networks. On a 2G (on GSM) network it supports up to 14 hours of talk time. It can download at maximum rate of 14.4 Mbps on a HSPA+ network such as AT&T Mobility's. On CDMA networks however it is limited to 3.1 Mbps, this includes Verizon Wireless's.

Operating system

Main article: iOS

iPhone 4S was announced with Apple’s iOS 5 operating system, which Apple claims as having 200 new features compared to the previous version. On the 4S, the Apple A5 processor and iOS 5 work together to support many subsystems of the device, such as data processing for the camera. Some major tasks performed include browsing the internet with Safari, voice assistance with Siri, cellular communications, media playback, and applications.
It supports PC and Mac freedom, where updates can be downloaded by over-the-air to the device.Another feature is the ability to have Apple send a real card in the mail with the Apple Cards application.

Accessories

Bumper

The bumper case designed for the iPhone 4 works on the iPhone 4S as well.

An iPhone 4/iPhone 4S Bumper is a ring of rubber and plastic that surrounds the edge of the iPhone 4S. The inner part is synthetic rubber with the external band made of plastic. It was released to deal with the reception issues and was available for free until 30 September 2010. A Bumper wraps around the edges of the device protecting the edges, and to a lesser extent, the screen. The Bumper does not cover the front or rear of the phone, though it does slightly raise it off whatever surface it is placed upon. Additionally, the plastic band houses metallic buttons for the volume controls and sleep/wake button. The six holes in the Bumper enable access to the mute switch, dock connector, headphone jack, speaker, and microphones. Bumpers are available for £25 each, in six colors: black, blue, green, orange, pink, and white.
Since the iPhone 4S has nearly the same design (mute switch has been moved slightly similar to the iPhone 4 CDMA model) some bumpers may fit both the iPhone 4 and iPhone 4S.

The iPhone 4 is a touchscreen slate smartphone developed by Apple Inc. It is the fourth generation iPhone, and successor to the iPhone 3GS. It is particularly marketed for video calling (marketed by Apple as FaceTime), consumption of media such as books and periodicals, movies, music, and games, and for general web and e-mail access. It was announced on June 7, 2010, at the WWDC 2010 held at the Moscone Center, San Francisco,and was released on June 24, 2010, in the United States, the United Kingdom, France, Germany and Japan.
The iPhone 4 runs Apple's iOS operating system, the same operating system as used on prior iPhones, the iPad, and the iPod Touch. It is mainly controlled by a user's fingertips on the multi-touch display, which is sensitive to fingertip contact.
The most noticeable difference between the iPhone 4 and its predecessors is the new design, which incorporates an uninsulated stainless steel frame that acts as the device's antenna. The internal components of the device are situated between two panels of chemically strengthened aluminosilicate glass. It has an Apple A4 processor and 512 MB of eDRAM, twice that of its predecessor and four times that of the original iPhone. Its 3.5-inch (89 mm) LED backlit liquid crystal display with a 960×640 pixel resolution is marketed as the "Retina Display".
The latest operating system release is iOS 5.0.1.
In October 2011, the iPhone 4S was announced, which retains the same form factor but includes some upgrades such as the A5 processor, iOS 5, and an improved camera.

History

Prototypes

Before the official unveiling of the iPhone 4 on June 7, 2010, two prototypes were brought to the attention of the media, breaching Apple's normally secretive development process. Many of the speculations regarding technical specifications proved accurate.

Gizmodo leak

On April 19, 2010, gadget website Gizmodo reported that they had purchased an iPhone prototype for $5000, and furthermore, had conducted a product teardown of the device. The prototype is reported to have been lost by an Apple employee, Gray Powell, in Redwood City, California. Shortly after Gizmodo published detailed information about the prototype, Apple's legal associates formally requested for the phone to be returned to Apple, and Gizmodo responded with the intent to cooperate. On April 22, officers from the Rapid Enforcement Allied Computer Team (REACT) task force of the California HTTAP Program raided the home of Jason Chen, the Gizmodo editor responsible for reviewing the prototype, seizing all of his computers and hard drives.The Electronic Frontier Foundation criticized the raid as violating journalist source protection laws that forbid the seizure of journalist computers as well as the suspicion that Apple had used its influence as a member of the steering committee which is charged with direction and oversight of the California REACT task force to push police into action in a way that would not normally be conducted for this type of incident. Apple had already received the iPhone prototype before the raid when it was returned by Gizmodo. The District Attorney has stated that the investigation has been suspended, and discontinued searching through the Gizmodo editor's belongings as they determine whether the shield laws are applicable, and cautioned that no charges have been issued at this point.

Taoviet leak

Pictures and video of a second prototype were published on a Vietnamese website, Taoviet, on May 12, 2010. It was almost identical to the first, and used an A4 chip manufactured by Apple. The website purchased the prototype for $4,000. DigiTimes reported that the screen resolution of the new phone was 960-by-640, which was confirmed by Apple at the iPhone 4's official announcement.

Release

Former Apple CEO, Steve Jobs, holding a white iPhone 4. The white iPhone 4 was released in April 2011.

The iPhone 4 was made available for pre-order on June 15, 2010. Customers attempting to pre-order the iPhone 4 reported problems with the pre-order process on the U.S. and U.K. online Apple Stores which crashed due to the surge in traffic. The same issue was reported with AT&T and SoftBank, Apple's exclusive partners in the United States and Japan respectively, who suspended advance sales of the iPhone 4 as demand threatened to exceed supply. Retail stores were also unable to complete pre-order transactions due to the servers crashing.Apple and its partner carriers received 600,000 pre-orders for the iPhone 4 in the first 24 hours, the largest number of pre-orders Apple has received in a single day for any device. Engadget reported that at 20:30 UTC, all iPhone 4 pre-order suppliers had sold out. 1.7 million iPhone 4s were sold in its first three days of availability.
The iPhone 4 has also been released through Orange in Tunisia and was available in eight cities at the launch. In South Korea, it was released by KT on September 10. In Israel, it was released, too, on September 24, through Cellcom, Pelephone and Orange. It was launched in Thailand on September 23 by AIS, DTAC and True Move, and in Malaysia on September 26 in Kuala Lumpur, and nationwide on September 27 according to the website of Maxis.The iPhone 4 was released in South Africa on September 22 on the Vodacom and MTN networks, in very limited quantities. The iPhone 4 was launched in Vietnam on September 30 by VinaPhone and Viettel, at first in 3 major cities: Hanoi, Ho Chi Minh city and Da Nang, and then all over the country by the end of October.
The iPhone 4 was launched in India on May 27, 2011 by Aircel and Airtel. Aircel is releasing the 16 GB iPhone 4 for 34,500 and the 32 GB one for 40,990. The smartphone will be available via contract from both service providers.
On January 11, 2011, Verizon announced during a media event that it had reached an agreement with Apple and would begin selling a CDMA iPhone 4 in the United States, ending Apple's exclusivity agreement with AT&T. The Verizon iPhone went on sale on February 10 and pre orders began on February 3. The Verizon iPhone includes the 'Personal Hotspot" feature which allows a user to use the iPhone as a wireless hotspot, with up to 5 devices connecting at one time. The February 3 presale of the iPhone 4 broke Verizon's first day sales records for a single device.
On June 24, 2010, Apple issued a statement that the white iPhone 4 models were proving more "challenging to manufacture" than expected, and initially pushed the release date back to the second half of July. There was a lot of speculation surrounding the delay of the white iPhone 4. Among the most popular rumors are those concerning the phone's internal camera being adversely affected by light leaking in due to the semi-translucent glass and the white paint. Other sources report that the problem relates to Apple's inability to match the white color of the front face plate with that of the home button.On April 27 Apple announced that it would be releasing the white iPhone 4 model on April 28, 2011 for both GSM and CDMA. The release of the white iPhone 4 was carried out on April 28, and is still available for purchase today.
During Apple's official unveiling of the iPhone 4S on October 4, 2011 it was announced that Sprint would begin carrying the reconfigured CDMA iPhone 4 and the iPhone 4S in the US on October 14.

Hardware

Display

The display of the iPhone 4 is manufactured by LG under an exclusive contract with Apple. It features an LED backlit TFT LCD capacitive touchscreen with a pixel density of 326 pixels per inch (ppi) on a 3.5 in (8.9 cm) (diagonally measured), 960×640 display. Each pixel is 78 micrometres in width. The display has a contrast ratio of 800:1. The screen is marketed by Apple as the "Retina Display", based on the assertion that a display of approximately 300 ppi at a distance of 12 inches (305 mm) from one's eye, or 57 arcseconds per pixel is the maximum amount of detail that the human retina can perceive. With the iPhone expected to be used at a distance of about 12 inches from the eyes, a higher resolution would allegedly have no effect on the image's apparent quality as the maximum potential of the human eye has already been met.
This claim has been disputed. Raymond Soneira, president of DisplayMate Technologies, said in an interview with Wired magazine, that the claims by Jobs are something of an exaggeration: "It is reasonably close to being a perfect display, but Steve pushed it a little too far." Soneira stated that the resolution of the human retina is higher than claimed by Apple, working out to 477 ppi at 12 inches (305 mm) from the eyes, or 36 arcseconds per pixel. However, Phil Plait, author of Bad Astronomy, whose career includes a collaboration with NASA regarding the camera on the Hubble Space Telescope, responded to the criticism by stating that "if you have [better than 20/20] eyesight, then at one foot away the iPhone 4’s pixels are resolved. The picture will look pixellated. If you have average eyesight, the picture will look just fine."

Camera

The iPhone 4 is the first iPhone model to have two cameras. The LED flash for the rear-facing camera (top) and the forward-facing camera (bottom, left of speaker) are not present in older models.

The iPhone 4 features an additional front-facing VGA camera, and a backside-illuminated 5 megapixel rear-facing camera with a 3.85 mm f/2.8 lens and an LED flash. The rear-facing camera is capable of recording HD video in 720p at 30 frames per second. Both cameras make use of the tap to focus feature, part of iOS 4, for photo and video recording.The rear-facing camera has a 5× digital zoom.

Connectivity

In contrast to Steve Jobs' announcement at WWDC 2010, recent Federal Communications Commission documentation has shown that the iPhone 4 contains a penta-band 3G UMTS antenna, not a quad-band 3G UMTS radio, as advertised by Apple. According to the FCC documentation filed by Apple, the radio inside the iPhone 4 supports 800, 850, 900, 1900, and 2100 MHz. The 800 MHz frequency, which is most commonly used in Japanese mobile phones, is not advertised as being supported by Apple. However, the 800 MHz band is a subset of the 850 MHz band, which probably explains why the device is advertised as quad-band.^{[citation needed]} The chip-sets were manufactured by Skyworks Solutions and Infineon for GSM version.
As with most of Apple's mobile products, the iPhone 4 also uses the 30 pin dock connector as its only external data port.
The iPhone 4 is the first generation of iPhone to have a second microphone used for noise cancellation. It is located on the top of the unit near the headphone jack; the main microphone is on the bottom left.

Gyroscope and accelerometer

The iPhone 4 introduces a gyroscopic sensor that detects 3-axis angular acceleration around the X, Y and Z axes, enabling precise calculation of yaw, pitch, and roll. The gyroscope complements the accelerometer, a sensor that has been present since the original iPhone, which detects the device's acceleration, shake, vibration shock, or fall by detecting linear acceleration along one of three axes (X, Y and Z). The combined data from the accelerometer and the gyroscope provides detailed and precise information about the device's 6-axis movement in space. The 3 axes of the gyroscope combined with the 3 axes of the accelerometer enable the device to recognize approximately how far, fast, and in which direction it has moved in space.

Processor and memory

The iPhone 4 is powered by the Apple A4 chip, which was designed by Intrinsity and, like all prior iPhone models, manufactured by Samsung.This system-on-a-chip is composed of an ARM Cortex-A8 CPU integrated with a PowerVR SGX 535 GPU.The Apple A4 is also used in the iPad where it is clocked at its rated speed of 1 GHz. The clock speed in the iPhone 4 has not been disclosed. All prior models of the iPhone have underclocked the CPU, which typically extends battery life and lowers heat dissipation.
The iPhone 4 has 512 MB of eDRAM. The additional eDRAM supports increased performance and multi-tasking.

Storage and Micro-SIM

The iPhone 4 uses a Micro-SIM card on iPhone 4 devices running on a GSM network, which is positioned in an ejectable tray, located on the right side of the device. On a CDMA network, however, the phone connects to the network using an ESN. All prior models have used regular Mini-SIM cards. Depending on the operator, Micro-SIM cards may not be available for all networks globally. As a technical workaround it is possible to trim a Mini-SIM card with a knife or scissors so that it fits into the Micro-SIM tray.
As on prior models, all data is stored in flash memory, 16 or 32 GB, and not on the SIM. Unlike prior generations, the storage capacity is not printed on the back of the unit.

Design

The iPhone 4 features a redesigned structure, designed by Jonathan Ive. Most notably, the bulges of the back panel as well as the band between the front and back are gone and have been replaced with flattened surfaces. The redesign reflects the utilitarianism and uniformity of existing Apple products, such as the iPad and the iMac. The overall dimensions of the iPhone 4 have been reduced from its predecessor. It is 4.5 inches (110 mm) high, 2.31 inches (59 mm) wide, and 0.37 inches (9.4 mm) deep, compared to the iPhone 3GS, which is 4.55 inches (116 mm) high, 2.44 inches (62 mm) wide, and 0.48 inches (12 mm) deep; making the iPhone 4 24% thinner than its predecessor, the iPhone 3GS. Steve Jobs claims that it is “the thinnest smartphone on the planet". The reduced size of the device is primarily due to the externally placed antenna.
The iPhone 4 is structured around a stainless steel frame that wraps around the edge of the phone, acting both as the primary structure for the device and as the iPhone 4's antennas. This metal band features two slits on the GSM version of the phone, one at the lower left, and one at the top (and a fake slit along the lower right, to cosmetically mirror the one at the lower left) that divide the band into two antenna sections: the left section of the band serves as the Bluetooth, Wi-Fi, and GPS antenna, and the right and lower sections of the band act as the antenna for GSM and UMTS connectivity. On the CDMA version of the phone, however, there are four slits in the metal band. Two at the top (on the left and right) and two at the bottom. This divides the metal band into four different segments, which like the GSM version of the phone, serves as different antennas for connectivity. The top portion of the band (divided by the top left and right slits) is for connecting to the CDMA network. The left portion of the metal band is for Bluetooth, Wi-Fi, and GPS just like the GSM version. The right side is not an antenna, but serves to cosmetically mirror the left side and also to create a similar look to the GSM version of the phone.
The internal components are situated between two panels of aluminosilicate glass, described by Apple as being "chemically strengthened to be 20 times stiffer and 30 times harder than plastic," theoretically allowing it to be more scratch resistant and durable than the prior models.
In fall 2010, pentalobular screws started to replace the Philips screws used in post-repair units in the US and in production units in Japan.

Software

FaceTime

The iPhone 4 supports FaceTime, an embedded video calling application that is able to use either the front or back camera over a Wi-Fi connection to communicate with another iPhone 4, the fourth-generation iPod Touch, an iPad2 or any Macintosh computer running Mac OS X 10.6 Snow Leopard.

Accessories

Bumper

An iPhone 4 next to a Bumper.

An iPhone 4 Bumper is a ring of rubber and plastic that surrounds the edge of the iPhone 4. The inner part is rubber with the external band made of plastic. The Bumper wraps around the edges of the device protecting the edges, and to a lesser extent, the screen. The Bumper does not cover the front or rear of the phone, though it does slightly raise the iPhone off whatever surface it is sitting on.
Additionally, the plastic band houses metallic buttons for the volume controls and sleep/wake button. The six holes in the Bumper enable access to the mute switch, dock connector, headphone jack, speaker, and microphones. The bumper also can be used to prevent the "antenna issue" that users face when holding the parts of the steel band where the antennas are, that could cause the phone's signal to drop^.

Technical issues

Some users have reported a yellow discoloration of the screen when they first received the phone which disappeared after several days, which was attributed to the glass lamination glue that was used. It did not have time to dry fully before the unit reached consumers due to the speed of manufacturing. Another issue reported by some users within days of the iPhone 4 release was that during calls the proximity sensor can be insensitive, so that facial contact with the touchscreen can end calls, mute calls, and dial other numbers.

Antenna

Shortly after the iPhone 4 was launched, some consumers reported that signal strength of the phone was reduced when touching the lower left edge of the phone, bridging one of the two locations which separates the two antennas, resulting in dropped calls in some areas with lower signal reception.In response, Apple issued a statement advising that customers should "avoid gripping [the phone] in the lower left corner" when making or receiving a call.
As a consequence of this problem, it was reported on July 2, 2010 that several iPhone 4 users were planning on suing Apple and AT&T for fraud by concealment, negligence, intentional misrepresentation and defective design. The legal challenge was started by California law firm Kershaw, Cutter & Ratinoff, who set up a website to recruit disenchanted iPhone 4 buyers for a lawsuit against Apple. Later that day, Apple issued another statement stating that it had discovered the cause of the "dramatic drop in bars". Apple explained how the formula it used to calculate the number of bars to display was "wrong". Apple promised to correct the issue and release a software update within a few weeks that would address the "mistake", which had been present since the original iPhone.The New York Times commented that "the failure to detect this longstanding problem earlier is astonishing."
Consumer Reports initially stated that the iPhone 4's signal issues are not "unique, and may not be serious" and it continued to mention that signal loss is a problem that is faced by the entire smartphone industry. It has been such a problem that Apple made a formal apology. The next day, the magazine altered their stance after encountering instances of dropped calls. The magazine rejected Apple's explanation after conducting tests in a controlled environment, and comparing the results against prior generations of iPhone. It sarcastically pointed out that using a piece of tape to cover the lower left antenna gap was one way to fix the problem, but recommended that consumers who "want an iPhone that works well without a masking-tape fix" purchase the iPhone 3GS instead. The magazine also tested the iPhone 4 while it was wearing a Bumper, a frame-like cover sold by Apple that prevents direct contact with the antenna, reporting that it did resolve the problem.^[72] CNN repeated Consumer Reports' statement that a small amount of duct tape had proven an effective fix to the iPhone 4's dropped call issue.
On July 16, 2010, at a press conference, Steve Jobs announced that Apple would provide all iPhone 4 owners with a free case to help solve the antenna issue and a refund to those users who had already purchased a Bumper. The free case offer would be valid until September 30, 2010, when Apple would re-evaluate the situation. To get a free case, owners were able to apply via an app installed on the phone found in the App Store from July 22, 2010 to September 30, 2010. Jobs also announced that Apple could not produce enough Bumpers for all owners of the phone, but would source a supply and offer a range of cases. Additionally, Jobs cited figures from AppleCare which showed that only 0.55 percent of all iPhone 4 users have complained to the company about the issue, while the number of phones returned to Apple was 1.7 percent – 4.3 percentage points less than the number of iPhone 3GS models that were returned in the first month of the phone's launch.
Consumer Reports noted that the solution was not permanent, though a good first step.However, because Jobs did not specify a time line for fixing the problem, and the offering for a free bumper only being a temporary solution, PC World decided to remove the iPhone 4 from its "Top 10 Cell Phones" chart and reassign it to a pending rating.
AnandTech researched iPhone 4 antenna and identified that its outer construction provides 5–9 dB (6.9–9 times) better sensitivity comparing to common internal antenna design of iPhone 3Gs (the phone keeps working connection with signal as low as −120/121 dB comparing to usual −113/115 dB).
Despite the negative media attention regarding the antenna issues, 72% of iPhone 4 users say that they are "very satisfied" with their iPhone 4 according to an August 2010 survey by ChangeWave Research.

Camera image fault

Reports about iPhone 4 cameras being rendered useless by a peculiar fault started to show up on the Internet in September 2010. Under certain lighting conditions the back camera produces a large green 'halo' in the center of the image. This renders many of these images to be of much lower quality than what the iPhone 3GS is capable of producing under similar lighting conditions. Reports started surfacing on forums and have since been picked up by major media sources.

Compass

The built in Compass application has a couple of minor software issues. In use it displays the iPhone's position at the bottom of the compass display (derived from the inbuilt A-GPS facility). While this positional information is correct for most of the world, there is a minor issue that if the longitude is greater than zero and less than one degree west of the meridian, the app incorrectly reports the longitude as being east of the meridian. This was fixed with iOS 5.0.
Also when crossing the date line, the longitude changes from 179°59'59" W directly to 179°59'59" E (or vice versa) missing out 180°0'0" E. Crossing the meridian, the display correctly shows 0°0'0" E

Critical reception

Reaction to the announcement

Media reaction to Steve Jobs' announcement of the iPhone 4 was generally positive. The announcement included information that had not been covered by Gizmodo. Fox News commented that "seeing it in action is far more informative than staring at Gizmodo's photos of a busted test unit".Rhodri Marsden of The Independent said that "aside from the introduction of face-to-face video calling, it's not a staggering feature set," instead focusing on how the device is "more powerful than its predecessor, speedier, easier to use and will make previously laborious tasks seem like a cinch".
CNET reacted to the announcement by explaining how it believes that iMovie for iOS was the "most exciting part of this year's WWDC Keynote". The article noted how the iPhone 4, unlike current cameras, can record HD content and then edit it from the same device, labeling it a "true mobile editing suite".

Reviews

Reviews of the iPhone 4 have been generally favorable. Walt Mossberg of The Wall Street Journal called the device "the best device in its class". Engadget named it the "best smartphone on the market" in June 2010. CNET gave the iPhone 4 a rating of 8.6 out of 10, one of the highest ratings it has given any smartphone. TechRadar gave the device 4.5/5 stars. Consumer Reports said the signal problem was the reason they did not rate it a "recommended" model, although the other tests ranked it highest among smart phones.
Joshua Topolsky of Engadget described the device's industrial design as being "more detailed and sophisticated" than its predecessor.

The iPhone 3GS (stylized iPhone 3G[S] by many blogs) is the third generation of iPhone designed and marketed by Apple Inc. It was introduced on June 8, 2009 at the WWDC 2009 which took place at the Moscone Center, San Francisco.
Its features primarily consist of faster performance, a camera with higher resolution and video ability, voice control, and support for 7.2 Mbit/s HSDPA downloading (but remains limited to 384 kbps uploading as Apple had not implemented the HSUPA protocol).It was released in the U.S., Canada and six European countries on June 19, 2009,in Australia and Japan on June 26, and internationally in July and August 2009.
The iPhone 3GS runs Apple's iOS operating system, as is used on the iPad and iPod touch. It is controlled mostly by a user's fingertips on a multi-touch display.
The iPhone 3GS is preceded by the iPhone 3G and succeeded by the iPhone 4.

History

The iPhone 3GS was made available for pre-order on June 8, 2009 and released on June 19 in Canada, the United States, and 7 European countries, and on June 26 in Australia and the United Kingdom. Within the first weekend of its release, over one million iPhone 3GS's were sold. July and August 2009 saw the release of the iPhone 3GS internationally. After the iPhone 4 was announced, an 8 GB (Black only) iPhone 3GS was released which was made available at a reduced price. Apple's decision to continue selling the iPhone 3GS alongside the iPhone 4 and the iPhone 4S makes the 3GS the longest running produced iPhone hardware to date.

Bootrom

iPhone 3GS models with new bootroms started appearing in mid-September 2009 which had blocked the "24k" exploit used in prior bootroms which were used mainly for iOS jailbreaking. This made devices with the new bootrom harder to jailbreak although not impossible. This marked the first time Apple slightly modified their devices midway through its supposed cycle (usually a one year cycle).

Features

The new features of the iPhone 3GS are mainly internal changes regarding speed, for which the "S" in "iPhone 3GS" stands.Though in addition to the upgrades mainly regarding performance, various software features were also introduced exclusive to the iPhone 3GS. All of the exclusive features were incorporated into the iPhone 4.

Display

The display on the device is designed by Apple and made by LG, it features an LCD capacitive touchscreen with a pixel density of 163 pixels per inch (ppi) on a 3.5 in (8.9 cm) 480-by-320 display. Improvements over its predecessor's screen include 24-bit color emulation (18-bit color display plus dithering) for a more color rich display and oleophobic coating to help reduce fingerprints on the display. The capacitive touchscreen is designed for a bare finger, or multiple fingers for multi-touch sensing.

Camera

The iPhone 3GS features an improved 3 megapixel camera manufactured by OmniVision. In addition to the higher megapixel count, it also features auto-focus, auto white balance and auto macro and is capable of capturing VGA video. The iPhone 3GS's Camera app features a slider which allows users to switch between capturing photos and recording videos, a tap-to-focus feature which allows users to tap on an area of the camera image to auto-focus on, 5x digital zoom (iOS 4 and 5), auto focus and auto exposure lock when holding an area down (iOS 5 only), and gridlines for composition (iOS 5 only).

Processor and memory

The iPhone 3GS is powered by the Samsung APL0298C05 chip, which was designed and manufactured by Samsung. This system-on-a-chip is composed of an ARM Cortex-A8 CPU core underclocked to 600 MHz (from 833 MHz), integrated with a PowerVR SGX 535 GPU.
It has 256 MB of eDRAM, twice the amount of the 3G, allowing for increased performance and multi-tasking.
Apple claims the iPhone 3GS is 2x faster than its predecessor, showing demonstrations of apps loading in just 2–10 seconds compared to 15–30 seconds on the iPhone 3G.

Storage

As on previous models, all data is stored in flash memory and not in the SIM and it does not offer any options to expand storage. Initially it was only available in 16 and 32 GB though an 8 GB model was later released, with Apple discontinuing the 16 and 32 GB models, forcing those needing more storage to select an iPhone 4, or buy an older model 3GS.

Power and battery

The iPhone 3GS is powered by an internal 3.7 V 1219 mAh rechargeable lithium-ion polymer battery and is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles. A battery life indicator in percentage was also exclusive to the iPhone 3GS.
Apple claims that the 3GS can last for up to ten hours of video, nine hours of web browsing on Wi-Fi, twelve hours of 2G talk time, or five on 3G, 30 hours of music, or 300 hours of standby.

Magnetometer

A magnetometer is also built-in the iPhone 3GS, which is used to measure the strength and/or direction of the magnetic field in the vicinity of the device. Sometimes certain devices or radio signals can interfere with the magnetometer requiring users to either move away from the interference or re-calibrate by moving the device in a figure 8 motion. The iPhone 3GS also features an exclusive Compass app which shows a compass that points in the direction of the magnetic field.

Connectivity

In addition to the iPhone 3G's tri-band UMTS/HSDPA radio and quad-band GSM/GPRS/EDGE radio, the 3GS also adds support for 7.2 Mbit/s HSDPA allowing faster downlink speeds though upload speeds remain the same as Apple had not implemented the HSUPA protocol. Other updates include the addition of a built-in Nike+iPod sensor which eliminates the need for an external sensor and allows native Nike+iPod support. The Bluetooth module on the iPhone 3GS has also been slightly improved adding support for Bluetooth 2.1 specifications.

Voice control

Voice Control was introduced as an exclusive feature of the iPhone 3GS and allows for the controlling of the phone and music features of the phone by voice. There are two ways to activate Voice Control: hold the Home button while in the home screen for a few seconds; or, change the effect of what double-clicking the home button does so it will activate Voice Control (only before iOS 4, where double clicking the Home button opens the multitasking bar).

Accessibility features

VoiceOver, Color Inversion, and Text Zoom were introduced as exclusive features to the iPhone 3GS. VoiceOver is a feature that dictates music details, system menus, text, and other things which was first introduced on the third generation iPod shuffle. Color inversion reverses the color scheme from black on white to white on black, while Text Zoom allows users to zoom into a text on the screen .

Design

The reverse of the iPhone 3G (left) is almost identical to that of the 3GS, differentiated only by the latter's reflective silver text which now matches the silver Apple logo, replacing the 3G's grey text.

The iPhone 3GS retains the same design its predecessor used which featured a glossy metal back with tapered edges which gives users a better grip of the phone. It also features metal buttons just like its predecessor's. The iPhone 3GS and its predecessor are almost identical though the 3GS is differentiated only by the latter's reflective silver text on the reverse side which now matches the silver Apple logo, replacing the 3G's grey text. Unlike its predecessor, the iPhone 3GS was available in white and black for both models (16 GB and 32 GB) although the current 8 GB model is only available in black.

Critical reception

Reviews

Reviews of the iPhone 3GS have been generally mixed to favorable. Walter Mossberg of The Wall Street Journal described the device packed with "new features that makes a great product even better, but for many users, the software may be enough of a boost to keep them from buying the new model."Engadget also criticized that "the additions of video recording, a compass, and a speed bump just don't seem that compelling to us". Still the device managed to receive numerous favorable reviews, CNET gave the iPhone 3GS a 4/5 stars citing the battery life improvements and speed bump alone are good enough although it might leave you wanting more, Engadget praised the performance improvements describing it "a bigger speed bump than you'll come to expect". TechRadar gave the device a 4.5/5 stars describing the device "feature filled but certainly not worth upgrading for"
However the 8 GB version of the device has received more favorable reviews mainly because it comes pre-installed with iOS 4. Jason Snell of Macworld praised the iPhone 3GS citing that "The device's internal changes shines in the iOS 4 update, making the iPhone 3GS a worthwhile upgrade compared to its predecessor although a little too late compared to the iPhone 4". TIPB cited that "aside from hardware specific features like FaceTime, Retina Display, and gyroscope support, the bottom line is iPhone 3GS users are getting the same software that makes the iPhone 4 great".

Issues

Overheating

Shortly after the release of the iPhone 3GS, some users reported overheating of the device while in heavy use, and others reported discoloration of the device due to heat (particularly on the white models). The discoloration issues were largely discounted as being as a result of iPhone covers rubbing against the back of the iPhone. Apple responded to the heat issue reports by warning users against leaving their iPhones in a car on a hot day, leaving it in direct sunlight for extended periods of time, and refraining from heavy usage while in a hot/sunny environment.It is also worth pointing out the temperature specifications in which the iPhone should be operated, which follows safety standards in the countries the 3GS was released.

Continued support

iOS 5

After the release of the iPhone 4S, the 3GS was still offered for free until November 2011, when AT&T raised the price to 99 cents with no explanation as to why. The 99c price is only available with a two-year contract on AT&T in the United States and a three-year contract on Telus, Rogers, and Bell and Fido Solutions in Canada. This is a departure from Apple's previous trends, in which only two phones are usually sold.

The iPhone 3G is the second generation of iPhone designed and marketed by Apple Inc.. It was the successor to the original iPhone, and is succeeded by the iPhone 3GS. Introduced on June 9, 2008 at the WWDC 2008 at the Moscone Center, San Francisco. The 3G was very similar to its predecessor, containing the same 2 MP camera and no support for video recording, and its performance was limited by the same 128 MB eDRAM memory unit.^[12] Nevertheless, the 3G featured several improvements over the original. It supported Assisted GPS, 3G data and tri-band UMTS/HSDPA.
The iPhone 3G runs Apple’s iOS operating system, the same operating system used on prior iPhones, and the iPad, Apple TV, and iPod Touch. It is primarily controlled by a user’s fingertips on the multi-touch display, which is sensitive to fingertip contact.
The iPhone 3G no longer receives software updates from Apple. The last release of iOS to support the 3G was 4.2.1, which was released on November 22, 2010. iOS 4.3, released on March 11, 2011, did not support the iPhone 3G

History

On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six; in 8GB and 16GB models, with the larger capacity version having the option of being in black or white. When the iPhone 3GS was released one year later, the iPhone 3G's price was cut in half, and was made the budget model of iPhone. The $99 iPhone 3G was in black only and came with 8 GB of storage. Included with this revision is iPhone OS 3.0 On June 7, 2010, the iPhone 3G was discontinued, and replaced with an 8 GB iPhone 3GS selling for the same price of $99.

Software

The iPhone 3G came preloaded with the latest version of iPhone OS both to offer the newest improvements to the software and to combat efforts of iOS jailbreaking. Over the years, the iPhone 3G has been supported by Apple with software updates. Major iterations of the software usually released yearly.
At launch, in July 2008, the iPhone 3G came preloaded with iPhone OS 2.0 which introduced the App Store, Microsoft Exchange ActiveSync support, Apple’s MobileMe service, and push email support, along with other new features and bug fixes as well.
On June 2009, the iPhone 3G received the iPhone OS 3.0 software update which introduced the long-awaited MMS feature, copy and paste, landscape support for more applications, Bluetooth stereo support, and other improvements as well.
On June 2010, the iPhone 3G owners were issued the iOS 4.0 software update. Unlike its successor, the iPhone 3GS, it did not receive multitasking, home screen wallpaper, or Bluetooth keyboard support. However, it still got the unified mailbox feature, folders, playlist creation, among other enhancements in iOS 4. Still despite the number of new features the update introduced, it was widely criticized for its slow performance on the device.
However an update to iOS 4.1 was unveiled and released on September 2010 which improved the device’s performance under iOS 4. Unlike other iOS devices though, it did not receive the Game Center application.
On November 22, 2010, the iPhone 3G received the iOS 4.2 software update, which included new features such as YouTube voting, and security fixes. The iPhone 3G however did not receive many features including AirPlay, more options in the multitasking tray, and Safari Text Search.
On January 12, 2011, the iOS 4.3 software update beta 1 was issued to developers. However, there are no iPhone 3G download links. The iPhone 3G is no longer supported by Apple in software updates.
On March 9, 2011, the iOS 4.3 software update officially announced, which was the first iOS software update leaving out the support of iPhone 3G.

Design

A rear view of the original iPhone (left) made of aluminum and plastic, and the iPhone 3G, made entirely from a hard plastic material.

The iPhone 3G's back features a redesigned plastic polycarbonate housing, replacing the aluminum back from the first generation. The buttons were also made from plastic to metal, and the edges of the phone were also tapered, providing a better grip of the phone. The iPhone 3G also introduced colors to the iPhone bringing black and white backs to the device. However only the 16GB version was available in both colors. The dimensions of the iPhone 3G were slightly larger than those of the original iPhone. It was 4.55 inches (116 mm) high, 2.44 inches (62 mm) wide, and 0.48 inches (12 mm) deep, compared to its predecessor, which was 4.5 inches (110 mm) high, 2.4 inches (61 mm) wide, and 0.46 inches (12 mm) deep.

Hardware

Screen and input

The 9cm touchscreen has a 320-by-480 (HVGA) resolution at 163 ppi, with scratch-resistant glass sitting on top of the display. The capacitive touchscreen is designed for a bare finger, or multiple fingers for multi-touch sensing.
The device also features the same sensors its predecessor had. A repositioned proximity sensor which deactivates the display and touchscreen when the device is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs from the user’s face and ears. An ambient light sensor adjusts the display brightness which in turns saves battery power. A 3-axis accelerometer senses the orientation of the phone and changes the screen accordingly, allowing the user to easily switch between portrait and landscape mode..

Processor and memory

Most of the iPhone 3G's internal hardware were based on the original iPhone. It still included a Samsung 32-bit RISC ARM11 620 MHz processor (underclocked to 412 MHz), a PowerVR MBX Lite 3D GPU, and 128 MB of eDRAM.

Camera

On the rear of the device, the iPhone 3G features the same fixed-focus 2.0 megapixel camera that its predecessor had. It had no optical zoom, flash, or autofocus, and does not support video recording, although various applications have allowed video recording on the device. The iPhone OS 2.0 software update which came preloaded on the iPhone 3G at launch, introduced the capability to embed location data in the pictures producing geocoded photographs.

Connectivity

In addition to EDGE, the iPhone 3G added Assisted GPS, 3G data, and tri-band UMTS/HSDPA. These enhancements allowed faster data downloads and turn-by-turn navigation with maps.
Like its predecessor and recent iPods, the iPhone 3G also features the same proprietary 30-pin dock connector for charging the device. It is also used to synchronize the device with a computer and to connect various accessories.
The iPhone 3G also features a flush-mounted 3.5 mm headphone jack instead of the recessed headphone jack that was included on the original iPhone, thus it can be used with headphones other than those provided by Apple.

Battery

The iPhone 3G features an internal rechargeable battery rated at 1150 mAh, which like its predecessor, is not user-replaceable. Apple states the iPhone 3G’s battery is capable of providing up six hours of web browsing on Wi-Fi, five hours on 3G and 25 hours of audio playback. It has 300 hours of standby. Unlike the first iPhone, the 3G uses a different battery which is fitted with a connector and is easier to replace. Replacement still voids the warranty if you don't use Apple's official service or third party suppliers which are authorized.
The battery life of the iPhone 3G has been criticized by several technology journalists as insufficient and less than Apple claims.

Software

Along with the iPhone 3G, the first major software update to iPhone OS 2.0 was released. It featured various new features and improvements over its predecessor, most notably the App Store.

App Store

Main article: App Store (iOS)

One of the main new features of iPhone OS 2.0 was the App Store, which allows users to install third party applications on their device. Before then, the only way to install custom applications on the device was via jailbreaking. On the App Store's initial launch, 500 applications were available for download, and this amount has grown dramatically since then. The software update was also issued to original iPhone and iPod touch users which also gave them access to the App Store although iPod touch owners were required to pay a fee to update to the new version.
A lot of other features were also given in iOS 2.0, making the iPhone 3G a full featured device at the time, having 3G data capabilities, 3rd party applications, and an updated OS that gave a lot of other software features, such as OS enhancements, extended language support, Mail/Contacts/Calendars updates, iPod (app) updates and Enterprise Support and enhancements for business users.

Issues

Hairline cracks

Since the iPhone 3G's public release, users have reported that there had been hairline cracks, especially on the white models.

Battery life

After the release of the iPhone 3G, many complaints were about battery life. This is also reflected by a J.D. Power and Associates custom satisfaction survey, which gave the “battery aspects” of the device its lowest rating of 2 out of 5 stars. That was after all of the firmwares and updates.

iOS performance issues

iOS 4, which was still compatible with the iPhone 3G, was released on June 21, 2010.
An article in the Wall Street Journal's Digits column on July 28, 2010 reported that iPhone 3G phones updating to iOS 4 responded slowly, had diminished battery life, and became excessively hot.
During a media event on September 1, 2010, Apple announced that iOS 4.1 would be released on September 8, 2010, claiming to fix issues with performance on the iPhone 3G, along with fixes for Bluetooth and proximity sensor issues and other updates.

iPhone

noreply@blogger.com (ceryfitz) — Mon, 9 Jan 2012 00:08:00 -0800

The iPhone—retroactively labeled the original iPhone, iPhone 2G, iPhone EDGE, or iPhone 1—was the first generation of iPhone designed and marketed by Apple Inc. It was announced on January 9, 2007 after months of rumors and speculation. It was introduced in the United States on June 29, 2007. It featured quad-band Global System for Mobile Communications (GSM) with General Packet Radio Service (GPRS) and Enhanced Data Rates for GSM Evolution (EDGE).
The original iPhone no longer receives software updates from Apple; its final firmware version was iOS 3.1.3.

History

Development

Steve Jobs, CEO at Apple Inc., conceived an idea of using a multi-touch touchscreen to interact with a computer in a way in which he could type directly onto the display, essentially removing the physical keyboard and mouse, the same as a tablet computer. Jobs recruited a group of Apple engineers to investigate the idea as a side project. When Jobs reviewed the prototype and its user interface, he conceived a second idea of implementing the technology onto a mobile phone. The whole effort was called the Project Purple 2 and began in 2005.
Apple created the device during a secretive and unprecedented collaboration with AT&T, formerly Cingular Wireless. The development cost of the collaboration was estimated to have been $150 millionover a thirty-month period. Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular Wireless gave Apple the liberty to develop the iPhone's hardware and software in-house.
The original iPhone was introduced by Steve Jobs on January 9, 2007 in a keynote address at the Macworld Conference & Expo held in Moscone West in San Francisco, California. In his address, Jobs said, "I have been looking forward to this for two and a half years", and that "today, Apple is going to reinvent the phone." Jobs introduced the iPhone as a combination of three devices: a "widescreen iPod with touch controls"; a "revolutionary mobile phone"; and a "breakthrough Internet communicator".

Release

The iPhone was released on June 29, 2007 in the United States where hundreds of people were reported to have queued outside Apple and AT&T retail stores days before the device's launch; with many stores reporting stock shortages within an hour. To avoid repeating the problems of the PlayStation 3 launch, which caused burglaries and even a shooting, off-duty police officers were hired to guard stores overnight.
It was later made available in the United Kingdom, France, and Germany in November 2007, and the Republic of Ireland and Austria in the spring of 2008.
Six out of ten Americans surveyed said they knew the iPhone was coming before its release.

Post-release

The iPod Touch, a touchscreen device with the media and internet abilities and interface of the iPhone, but without the phone application, was released on September 5, 2007. At the same time, Apple significantly dropped the price of the 8 GB model while discontinuing the 4 GB model. Apple sold the one millionth iPhone five days later, or 74 days after the release.After receiving "hundreds of emails...upset" about the price drop, Apple gave store credit to early adopters.
A 16 GB model was released on February 5, 2008.Apple released an SDK on March 6, 2008, allowing developers to create the apps that would be available starting in iPhone OS version 2.0, a free upgrade for iPhone users. On June 9, Apple announced the iPhone 3G, which began shipping July 11.The original iPhone was discontinued at that time; total sales volume came to 6,124,000 units.
While most Apple literature simply called the device "iPhone," the term "the original iPhone" appears in a press release from July 2010.

Design

The combined metal and plastic rear is unique to the original iPhone.

The original iPhone's design was centered on a 3.5 inches (89 mm) glass multi-touch touchscreen display. The original iPhone introduced five physical buttons that have remained consistent over newer generations of iPhone. The device featured a chrome plated metal frame. The back of which was made of brushed aluminum with a black plastic base, required because metal shields cellular and Wi-Fi signals. The camera was located in the upper-left corner of the iPhone's rear. The headphone socket was recessed into the casing, making it incompatible with most headsets without the use of an adapter. Other models do not have this issue.

Software

During release, the iPhone was marketed as running "OS X". The name of the operating system was revealed in the iPhone 2.0 SDK. Apple has released 4 major software versions for the iPhone and one major release in the beta period, including the one bundled with original iPhone units.
Currently, software updates for the original or "2G" and 3G iPhones have been discontinued. However, unlicensed third-parties are known for creating custom firmwares for the iPhone, as well as porting Android OS onto the iPhone.

Software history

The original release of the operating system included Visual Voicemail, multi-touch gestures, HTML email, Safari web browser, threaded text messaging, and YouTube. However, many features like MMS, third-party apps, and copy and paste were not supported at release. These missing features led to hackers "jailbreaking" their phones which added these missing features. Official software updates slowly added these features.
iPhone OS 2.0, released July 11, 2008, introduced 3rd party applications, exchange support, push e-mail, and other enhancements.
iPhone OS 3.0, released June 17, 2009, introduced copy and paste, and new YouTube features. Not all of the features of iPhone OS 3.0 were supported on the original iPhone.
The original iPhone did not receive the iOS 4 software upgrade, due to hardware constraints.
