On Thursday, September 22, the iCloud Backup data will be reset. Backing up to iCloud or restoring from an iCloud backup will be unavailable from 9 AM PDT – 5 PM PDT. If you attempt a backup or restore during this time, you will receive an alert that the backup or restore was not successful. After this reset, you will be unable to restore from any backup created prior to September 22. A full backup will happen automatically the next time your device backs up to iCloud.

Apple’s iOS 5 has been undergoing developer testing since its announcement back in June. Developers have been able to test iCloud for backups and storage during the developer betas.

Apple has provided 7 betas to developers thus far, and had been previously rumored to be offering the Golden Master (final version before release) on September 23rd. That same rumor had also incorrectly pinpointed a Beta 8 release a few days ago, but the 23rd date seems to line up nicely with this iCloud backup reset.

Apple had said that iOS 5 would launch “this fall” which technically begins on September 23rd.

As we said in the past, jailbreakers like P0sixninja, Saurik are participating in this event. We will be reporting offline about the new announcements from the MyGreatfest. As of now P0sixninja has found 5 new user land exploits for the iPad 2 and the upcoming iPhone.

Belkin may soon have an answer for those users, as DailyTech notes that the company is using this week’s Intel Developer Forum to show off a new docking station offering essentially the exact same connectivity as found on the back of Apple’s new display.

The Belkin Thunderbolt Express Dock features three USB ports, a Thunderbolt port for daisy chaining, a Firewire port, and a GbE port. This is basically the same port setup that’s found on the new 27” Apple Thunderbolt Display.

For Apple users looking for expanded port offerings via the Thunderbolt port and don’t want to pay $999 for the functionality, the Belkin Thunderbolt Express Dock will come in handy.

Unfortunately, there is no word yet on pricing or a launch date for the docking station, so users will have to wait for Belkin to release more details.

The released version is little buggy, but the developer promised to release an update in few hours. This jailbreak tweak has an option page under settings, so you can customize the tweak to swipe to close, show close buttons, show app title and much more. Overall I liked the options which gives control over it.

Here is a quick video demonstration coming after the break

CardSwitcher is available from Cydia for $1.99.

According to iPhone Dev Team

We’ve also added some overall improvements for old-bootrom 3GS owners (where the 24kpwn exploit applies):  on those devices, you can tell redsn0w to untether 4.3.5 and lower, or iOS5b7.  Old-bootrom 3GS owners can once again choose custom logos, and/or verbose booting (for the really nerdy iPhone3GS fans out there!).  And it allows 4.3.4 or 4.3.5 users to use ultrasn0w again.

This is a tethered jailbreak, so its mandatory to use iBooty for booting your iDevice.

Supported iOS device

iPhone 3GS (new bootrom)
iPhone 4 (GSM)
iPhone 4 (CDMA)
iPod Touch 3G
iPod Touch 4
iPad 1G

We’ll be on the lookout for new features and changes in this release, which comes just 12 days after beta 6 was released. In addition to iOS 5 Beta 7, Apple has pushed Xcode 4.2 Developer Preview 7, iTunes 10.5 beta 7, and Apple TV Software beta 6.

Here is a screenshot of Linux running on the iPad 1 and iPod Touch 4

The team will soon release a software based tool to easily install and run Android and Linux operating system on your iDevice.

In the email, Apple notes that beta subscribers will receive an additional 3 months free with their $24.99 paid subscription to cover the beta plus the standard 12 months after launch.

Apple also advises customers to maintain a local backup of their iTunes library and any music they add to iCloud. “Apple will periodically reset your iCloud library during the beta and it is critical that you backup your music regularly. Some features and optimizations of iTunes Match will not be available during the beta.”

iTunes Match will give users the same benefits for their downloaded and ripped music as those purchased from the iTunes Music Store, up to 25,000 songs, for $24.99/year.
