Jailbreakers rejoice, the long awaited and highly anticipated untethered jailbreak for iOS 5.0.1 on the iPhone 4S and iPad 2 is finally available.
It was only a few days ago that the first untethered iOS 5.0.1 jailbreak was shown off on video. It was functional, but declared to still be in testing. Fast forward just 4 days later, and a public release is available for all to download. The Chronic Dev team have announced they have packaged the exploits that allow execution of unsigned code (code named Absinthe A5) into a working untethered jailbreak. Both the iPhone 4S (GSM and CDMA variants), as well as the iPad 2 (GSM, CDMA and Wi-Fi only variants) are targeted and supported in this release.
It took a mass of crash reports, over 10 million, and almost 10 months of work for the team to find an entry point and exploit the new A5 chip. The exploit consists of a series of both userland and kernel level exploits that were dubbed ‘corona’. The name comes from a vulnerability that was in Apple’s IPSec IKE daemon, named ‘racoon’. Although the app released today, for jailbreaking current iPhone 4S and iPad 2 devices, is only available for Mac OS X users, there is a placeholder for Windows and Linux users. Their respective applications will likely be available soon and will be as simple as a point and click.
In addition to the tools being released, the “iOS Hacking Dream Team” has spawned. It consists of members from the Chronic Dev team (posixninja, pod2g and nikias) and the iPhone-dev team (planetbeing). Both teams have donation pages to thank them for their work and provide funds for hardware upgrades to ensure future devices can be jailbroken.
