iOS hacker pod2g has collated all missing pieces of exploits required for the new iOS 5.1 untethered jailbreak on all A5/A5X iOS devices which includes the new iPad (iPad 3), iPad 2 and iPhone 4S. Pod2g is currently exploring a way to bypass ASLR security at Bootup. The confirmation came via his official twitter account. Those who accidentally updated their iPhone 4S and iPad 2 device to iOS 5.1 without paying heed to our warnings, will soon be able to jailbreak their iOS device.
What is ASLR?
ASLR (Address Space Layout Randomization) was introduced by Apple in iOS 4.3 which randomize data on the RAM to help prevent exploits from taking control of the system. To know more about ASLR technique, you may read the slides presented by hacker Stefan Esser at POC 2010.
Those who are unaware, pod2g was responsible for discovering the A5 jailbreak vulnerability which led to a successful untethered iOS 5.0/iOS 5.0.1 Jailbreak using Redsn0w (for A4 Devices), Corona (A4 Devices) and Absinthe (for iPad 2 and iPhone 4S) jailbreak tools.
The new iOS 5.1 Jailbreak Release Date?
Hacker chpwn, who is close to the internals of the jailbreak scene, claims that just because all the exploits are found doesn’t mean that a jailbreak exists – it’s likely months away from first working at all. Moreover, pod2g hasn’t given any ETA, details about the exploit being discovered or the tool onto which it will be packaged – greenpois0n or redsn0w or Absinthe.
Plausibly, he will hold back the release till Apple pushes iOS 5.2 or an incremental iOS 5.1.1 software update. And if you want to keep your hopes alive, have patience and hold off on upgrading to any incremental update until pod2g jailbreak is publicly available.
Stay tuned for more info as it happens about iOS 5.1 untethered jailbreak.
