As mentioned by iOSnoops earlier this week, the exploit uncovered by iPhone security expert i0n1c is about to make its way into jailbreak tools such as redsn0w and PwnageTool. Dev Team member MuscleNerd recently confirmed that the exploit was indeed working with iOS 4.3, as well as iOS 4.3.1, and that only a few minor bugs needed to be squashed before a solution is released, most likely within the next couple of days. The upcoming tools using i0n1c’s exploit will be compatible with iPhone 3GS, iPhone 4, third and fourth generation iPod touch, as well as first generation iPad. iPad 2 users will need to wait, as the tablet uses a different kind of bootrom that renders the exploit ineffective.
Over the last couple of months, iOS updates have become increasingly effective against jailbreaks. For instance, and for the first time since the iPhone hit store shelves in 2007, Apple recently managed to block a jailbreak method before it was released, via the iOS 4.3.1 update. The exploit, uncovered by Comex, would have allowed users to jailbreak iPad 2s running iOS 4.3.
