However some folks wanted to use it on their iPhone 3GS, but since there were restrictions on the installation of the package it wasn’t possible. You can get around this restriction by modifying the plist.info within the Application. Exact instructions on how to do this can’t be provided as Apple will take action. Here’s the instructions.

“just download the file, modify info.plist file and change the Minimum system version to 3.0.0 and UIRequiredDeviceCapabilities/front-facing-camera to false”

Redmondpie has put up a video of the iMovie on a 3GS.

The information comes from random sources so its not yet confirmed. However, this tweet from @ih8sn0w that states if you’ve saved your 3.1.2 SHSH blobs then its possible to Jailbreak your new Bootrom 3GS on iOS 4.

The cool video here –http://www.youtube.com/watch?v=NWc_d2C5TME // Is indeed real, but requires the 3.1.2 SHSH blobs. [Tweet Link]

Here’s the video embedded for your viewing pleasure.

He also just tweeted the following.

Alright… If anyone has their 3.1.2 SHSH blobs, NOT 3.1.3. Then I’ll see if I can produce a tool that will do this job… [Tweet Link]

This is really good news, it will mean all the pre-iPhone 4 devices can now be Jailbroken on iOS 4.

Recently the Unlock for the all of the available 3G/3GS Baseband’s  was released. Which now provides loads of people the choice of changing carriers or using a pay as you go SIM when travelling.

The iPhone 4 is a different beast however, and this is why there isn’t an Unlock available at this point. Even though Geohot has posted on Twitter that he has an unlock called iPwn that unlocks all devices for life, and he won’t be releasing it anytime soon. You can read the article at redmondpie.com

The infamous iPhone hacker George Hotz (aka Geohot) is in France these days, taking part in Nuit Du Hack conference which is currently being held in Paris. During his presentation at the conference, he mentioned that he has found a new bootrom exploit, which can ultimately pwn all iPhones for life, including the yet to be released iPhone 4. He has named this exploit as “pwned4life”.

He’s referenced the iPhone 4 and Jailbreaking/Unlocking in his tweets recently.

@comex not sure why you wrote I am about to release. like you, I don’t even own an iphone 4. [Tweet Link]

I realize most of you aren’t dicks. I have some cool stuff planned, but not the time to make it how I envision it now. Keep an eye on spirit [Tweet Link]

As you can see, right now its not Geohot’s priority to do anything about the iPhone 4 Jailbreak/Unlock. However he has somethings in store.

Here is some more information that the iPhone-Dev’s have discovered.

The DevTeam and others have been checking through the iPhone 4, and have noticed the baseband runs a completely different OS than on previous models. The iPhone 3G and 3G[S] both ran Nucleus OS on the PMB8878 baseband CPU (aka XGold 608), where the iPhone 2G ran the PMB8876 (aka S-Gold 2). iPhone 4 uses the PMB9800, or X-Gold 618 – running a separate OS – ThreadX, an RTOS by ExpressLogic.

So now we just wait, as the iPhone 4’s make their rounds to all their owners in different places. We should see more news about the iPhone 4 unlock/jailbreak.

• First iPhone (2007) at US $ 217.73.
• iPhone 3G (2008) at US $166.31
• iPhone 3GS (2009) at US $ 170.80

So the markup can be figured out pretty easily, since I live in Canada I know what they’re going to sell the iPhone 4 at. They’ve said $699 CAD, so you can do the math. At this point I’m going to be hanging onto my 3GS, just because I don’t think I need the iPhone 4 I need to wear out my 3GS before I can buy it.

Here is a breakdown chart provided by machackpc.com that states how much each portion costs Apple.

Think I’m the first one I know about to get a root shell (and SSH) on iPhone 4, using poor @comex’s code (since he has no iPhone 4). [Link to Tweet]

The next piece of information was from @musclenerd from the iPhone Dev team.

Congrats to @comex for another userland JB http://is.gd/d5N6I <– hi-res Cydia via @planetbeing & @chpwniPhone4s [Link to Tweet]

Here is the screenshot of a Hi-Res Cydia in @musclenerd’s tweet and one from a root shell.

However, this doesn’t mean that you will be able to Jailbreak your iPhone 4 anytime soon. Why? Well it looks like the Jailbreak was successful for the iPhone hackers, however what is required cannot be distributed because it contains some Apple Code that would cause legal ramifications. The Jailbreak uses the same method as Spirit which seems to not been patched by Apple properly in the newest Firmware iOS4.

There was a couple of Tweets after all of this excitement from another iPhone hacker but he is not affiliated with the iPhone Dev team. His name is @p0sixninja and this is the Tweets I’m talking about.

@i_Enthusiast the jailbreak shown is a more of a stepping stone for us, it can’t be released because it includes some of apples software [Link to Tweet]

And one from @planetbeing regards when the possibility of the Jailbreak being available to the public.

Don’t want to speak for @comex, but afaik no one has breathed a word about release date and what we have right now is nowhere ready. [Link to Tweet]

With the release of iOS 4.0.1 and the current work that needs to be done for a Public Jailbreak, I don’t see this happening for well over a month. However, we’ve seen things happen in shorter time and this release will be one of the major highlights of the year for iPhone hacking.

This new version doesn’t add support fr iOS4 or the iPhone 4 at this time, you can download and read more about the progress of Spirit at their website. Oh and Spirit works on Windows/Mac/Linux.

You can download the program from the iH8sn0w.com website here. I’ve also mirrored the utility on our site as well to make sure its available even if MediaFire goes down.

Windows Download:  iDetector 1.0 (62)

Why would you need to know this in the first place? The current Jailbreak out for iOS4 on the 3GS only works on the Old Bootrom (359.3). If you don’t check, and you try the JailBreak on your phone, you could come into some problems. Always make sure that you have saved your SHSH Blobs for your iPhone.You should have iOS3 and iOS4, if not then you can always use Saurik’s server to be able to restore if they’re present on his server. You will know if this is true when you open Cydia and it says “This device has SHSHs on file for iPhone OS: 3.0, 3.1, 3.1.2″. As long as you have one of them you can restore back to 3.x.x, the following screenshot shows what it will look like in Cydia.

Otherwise if you don’t have your SHSH’s for iOS3, you will have to restore your iPhone to iOS4 without a Jailbreak, and will only be able to use userland Jailbreaks in the future from what I understand.

Here is more information on how Tiny Umbrella works, this is directly from their website thefirmwareumbrella.blogspot.com

If you have one of the following devices:

• iPhone 3GS
• iPod Touch 3rd Generation (32 or 64)
• iPod Touch 2nd Generation (with a model number MC)

Then you have probably noticed that Apple does not let you go back down to older firmware versions for your device. Once you ‘upgrade’ they don’t let you downgrade. The way they stop you is basically by a simple response that iTunes receives when you try to restore the firmware of your choosing. See, the firmware is now signed for the above devices. It is signed with a unique id (ECID) that only your device has. Apple takes the firmware version files and combines them with your ECID and generates a hash that ONLY APPLE can generate. iTunes packages up this valuable information and sends it to your device. Your device checks the information and verifies the signature (making sure it really came from Apple because it CANNOT be forged as the encryption is very high). If the signature matches then the restore process can continue. If the signature does not match, the device raises an error and the restore process stops. Thanks to Saurik (Jay Freeman) we all now know how to circumvent this. Apple only provides this signature for firmware versions while the firmware version is ‘Active’. So once a new firmware version is out, Apple stops signing the older version and only signs the new version. This is why you cannot get 3.1.2 signatures anymore. Apple is currently only signing 3.1.3 signatures (and 3.2 for iPads). This will change when the next firmware is released. Soon 3.1.3 (and 3.2) firmware signatures will be a thing of the past and Apple will only sign the next one. The version is important. If you do not have the EXACT signatures for the exact device (ECID) for the exact firmware version, you cannot restore that device to that version. PERIOD. So, if there was a way to save that signature for later use, we could bypass the need for asking Apple (only to have them say ‘No’) to restore our firmware. If you have a jailbroken device, you can visit cydia and your shsh will be saved ‘on-file’. But if you are not jailbroken yet, or if a jailbreak has not yet been released for the firmware your device is on, you are just out of luck as you can only get cydia if you are jailbroken. This is where TinyUmbrella comes in.

I’ve compiled the following Guide on how to store your SHSH Blobs using TinyUmbrella.

Step 1: Download TinyUmbrella from thefirmwareumbrella.blogspot.com for your OS (Windows/Mac)

Step 2: If you’re using a Mac, double click on “Umbrella-4.00.26.dmg” and drag the Application within the .dmg file to your desktop. Otherwise you will have issues. For Windows just run the file from where ever you have downloaded it to.

Step 3: Run TinyUmbrella and plug in your Device (3GS/iPad/iPhone4/iPod Touch). It will then display your Firmware currently on the Device, as well as the device Model/Baseband and other informaiton.

Step 4: Click “Save My SHSH”, and the program will save your SHSH for your device base on whichever Firmware is currently being singed by Apple. And in this case its 4.0, which you can see below in the screenshot. The Firmware 3.x.x is no longer being signed.

You should now be able to restore your iPhone at anytime to 4.0 using the SHSH you’ve just generated using the same tool. Just click Start TSS Server, make sure its running like in the Screenshot shown below.

Then you just need to Open iTunes 9.2 and do a restore making sure you hold down “Alt + Shift” for Windows and “Option” for Mac when clicking restore. Then you should be able to restore your iPhone to whatever Firmware you’ve generated and saved SHSH keys for.

ToolJail provides information about your iPhone and iPod Touch that allows you to Jailbreak and Unlock your iPhone. There are also guides on how to Jailbreak your device, including steps on how to get into DFU and Restore Mode. The Microsoft .NET Framework 3.5 is required to be install in order to run ToolJail. You can download it here.

Download .NET Framework 3.5 (required to run ToolJail)

There are a bunch of RapidShare links to download ToolJail however. However they seem to be broken. I’m looking for the download and will host it locally for you. Here is the RapidShare Link.

And here is the download hosted by iphonenewbs.com

For Mac users, the iPhone 3G and 3GS required OS 10.4 to sync. And while we’re a little late on reporting it, we know it will affect some users all the same. iPhone 4 requires OS 10.5.

For many of us, it doesn’t matter. We’re on OS 10.6 by now. But there’s no real logic as to why, if older OSs can run iTunes, they can’t sync with new iPhones…especially when you look at how well Apple supports iPhones on the PC. You can sync an iPhone 4 to any PC running Windows 7, Windows Vista, or Windows XP (SP3).

Engadget - The Jimmy Fallon Test: is the iPhone 4 dropping fewer calls?

Engadget - Hey Apple, you’re holding it wrong!

Gizmodo – Steve Jobs Shows Cool Antenna Trick to Russian President

There is even an email from Steve Job’s from a customer who just bough an iPhone where Job’s responds with “Just avoid holding it that way”. Source

I ran into this blog post by Spencer Webb who works for AntennaSys Inc, that talks about the design of the iPhone 4 Antenna. You can read his article “iPhone 4 Antenna”, I’ve included some quotes of his article. It’s an awesome read and concludes the reasons behind their choice and how almost all Cell Phones have issues with reception based on their design and how the users holds them.

I saw the photo of the frame of the iPhone in the slideshow at the end of Steve Job’s keynote address at the Developer’s Conference.  There are three gaps in the stainless steel band which are allegedly part of the antenna system.  I have not had alot of time to analyze their structure, nor do I have one in my hands yet.  So, either it is public relations hokum, or those slots are really part of the antenna structure.  They do appear to be active, based on observations.

In the first generation iPhone (which I am currently using), the antennas were on the back of the phone, near the bottom.  There was a piece of plastic on the bottom covering the antennas, so you knew where they were.  I developed a way to hold the phone which avoided covering this area with my hand, similar to the Gizmodo article linked above.  It is worth stepping back a moment and asking the question, “Why are the antennas placed where my hand is MOST likely to cover it?”  It’s a fair question.

The FCC puts strict limits on the amount of energy from a handheld device that may be absorbed by the body.  We call this Specific Absorbtion Rate, or SAR.  In the olden days, when I walked ten miles to school in three feet of snow, uphill in both directions, cell phones had pull-up antennas.  This allowed the designer to use a half-wave antenna variant, and put the point of maximum radiation somewhat away from the users cranium.  Of course, most people did not think it was necessary and kept the antenna stowed.  Motorola’s flip phone acutally had a second helical antenna that was switched into place when this was the case.  But, more importantly, SAR rules were not yet in effect.

Flip phones became yesterday’s style, and phones were becoming more monolithic.  Some phones, like the early Treo, kept the antenna in the traditional location at the top of the phone, near one edge, but reduced it to a short stub.  Whips became stubs, stubs became bumps, and finally antennas were embedded into the rectangular volume of the phone.  The trouble was SAR; if you left the antenna at the top, the user was now pressing it into their head, insuring lots of tissue heating.  Enter the bottom-located cellphone antenna.

Just about every cell phone in current production has the antenna located at the bottom.  This insures that the radiating portion of the antenna is furthest from the head.  Apple was not the first to locate the antenna on the bottom, and certainly won’t be the last.  The problem is that humans have their hands below their ears, so the most natural position for the hand is covering the antenna.  This can’t be a good design decision, can it?  How can we be stuck with this conundrum?  It’s the FCC’s fault.

You see, when the FCC tests are run, the head is required to be in the vicinity of the phone.  But, the hand is not!!  And the FCC’s tests are not the only tests that must be passed by a candidate product.  AT&T has their own requirements for devices put on their network, and antenna efficiency is one of them.  I know because I have designed quad-band GSM antennas for the AT&T network.  The AT&T test similarly does not require the hand to be on the phone.

So it makes sense what Apple was trying to do, however why wasn’t any of these problems brought up when the iPhone 4 was designed and tested. I mean they must have left handed employees testing these devices. Furthermore why not disclose that it needs a bumper or include one? It all seems to be rather strange. Anyways, the closing statement tops it off.

So, what’s an iPhone lover to do?  Well, I voted with my dollars.  I ordered my iPhone 4 to replace my Original.  I already know how to do the Vulcan Antenna Grip on the iPhone, and I am wearing out my current model.

And sometimes an antenna that’s not great, but good enough, is good enough.

At this point I’m still debating my purchase of an iPhone 4, I will see how everything pans out. I might buy a iPhone 4, I might not. I shall see what occurs down in a months time.

However, if you’re with AT&T or some other provides that don’t support HSUPA, then you will not see an improvment.

Jobs: That’s ‘theoretically’ because the carriers don’t support it yet

In the US, AT&T’s 3G HSDPA primarily maxes out at 3.2 Mbps, with typical speeds ranging from 0.7 to 1.7 Mbps. The company is in the process of deploying faster 7.2 Mbps service, but this is currently limited to just a few cities: Charlotte, Chicago, Dallas, Houston, and Los Angeles and Miami.

In terms of uploads, AT&T’s 3G HSUPA network operates with typical speeds ranging from 0.5 to 1.2 Mbps, roughly two to four times faster than 0.3 Mbps theoretical maximum of the non-HSUPA capable iPhone 3GS. Not all of AT&T’s 3G network supports faster HSUPA service.\

Outside the US, several mobile operators in Canada, Europe, Asia, and Australia have been supporting 7.2 Mbps or faster HSDPA for more than a year (with some offering even faster 14.4 Mbps or better service) and 1.4 to 5.8 Mbps HSUPA speeds. Even faster HSPA+ networks have started offering 21.6 Mbps downloads over the past year.

Here is a comparison to the 3.5G HSDPA/HSUPA on the iPhone 4G and the Wireless N Speeds (802.11n).

It would be very interesting to find out what Rogers/Telus are supporting on their towers. I haven’t had many issues with download or upload speeds.
