Jailbreakers And Unlockers:

There are a  few things you should know about iOS 4.2’s upcoming jailbreak and unlock before you upgrade:

  • You need to save iOS 4.1 SHSH blobs to Cydia if you want untethered iOS 4.2 jailbreak.
  • The untethered-ness of iOS 4.2 jailbreak will be of the userland nature i.e. it works on non-vital code and can be easily patched by Apple.
  • If you rely on carrier unlock, stay far away from this until updated PwnageTool / Sn0wbreeze comes out.
  • The jailbreak will support all iOS devices and all firmwares capable of being jailbroken.
