MuscleNerd of the iPhone Dev Team has just announced via Twitter that they’ve figured out a way to use the PwnageTool, limera1n exploit and Comex’s kernel hacks to jailbreak future firmwares (so iOS 4.2 and beyond) for all A4 chip based devices such as iPhone 4, iPod Touch 4G, iPad and new Apple TV.
It looks like the cat and mouse game between Apple and the iPhone hacking community is going to be even more interesting with this breakthrough.
MuscleNerd announced this via Twitter:
Think we've figured out a way to extend PwnageTool+limera1n+@comex hacks to untethered JBs for all future A4 firmwares 🙂
The USB exploit used by Geohot in limera1n is a low-level bootrom exploit that can’t be patched by Apple at least in case of existing iDevices. Apple will be able to only prevent jailbreaking in newer devices by patching the bootrom exploit.
The kernel hacks by Comex of the JailbreakMe fame will help the jailbreak to be untethered. Tethered means that the jailbreak needs to be reapplied every time you power down your jailbroken iDevice. If you let the battery run out or restart it then you will need to jailbreak it again by connecting to your computer (tethering).
iPhone Dev team will be using Geohot’s USB exploit and Comex's kernel hacks in PwnageTool to allow users to create a custom pre-jailbroken iOS firmware file so that they can update their iDevice and also preserve the baseband.
iPhone Dev Team is expected to release PwnageTool for iOS 4.1 for iPhone and iPod Touch and iOS 3.2.2 for iPad tomorrow.
What do you think about the possibility of an untethered jailbreak for life? Let us know your thoughts in the comments.
