Apple released iOS 6 beta 1 to developers on the first day of WWDC 2012. The iOS hackers have been working on jailbreak since then. @pod2g seemed to have some exploits even before first beta of iOS 6 was released by Apple.

iPhone Dev Team member, @MuscleNerd tweeted that a developer-only redsn0w version is released for jailbreaking iOS 6 beta on iPhone 3GS and A4 devices including iPhone 4 and iPod Touch 4. This redsn0w build is not compatible with A5 devices including iPhone 4S, iPad 2 or the new iPad. First gen iPad is also not compatible. Apple has patched jailbreak exploits in iOS 6 beta 1. A4 devices are compatible because of the limera1n exploit released by Geohot in 2010.

Here are some features of redsn0w jailbreak for iOS 6 beta:

  1. This release is only for developers. Cydia will not be installed. Only SSH access will be given.
  2. Gevey Sim or ultrasn0w unlockers should stay away from iOS 6.
  3. The jailbreak is tethered.
  4. Redsn0w will not hacktivate. You need a Apple developer account to get iOS 6 beta IPSW & your iOS device UDID should be registered with Apple.
