The news on iPhone 4S jailbreak, I believe we have been waiting a long time. Recently, MuscleNerd released the latest escape dynamics on Twitter. The Dev Team has already jailbreak iPhone 4S, but the jailbreak tool does not forthcoming.
MuscleNerd said on Twitter, now we can jailbreak iPhone 4S, but that still at a very preliminary stage and still exists serious issues, there are many work to do. He also released screenshot on Twitter.
yeah same for iPad2 (but with the same big hurdles ahead too before a public release is possible)


In addition, @MuscleNerd on Twitter also shows a jailbroken iPad 2 running iOS 5, but the same situation with the iPhone 4S, also to overcome many difficulties before the official release.
MuscleNerd also confirms that the new bootrom exploit used in this iPhone 4S jailbreak is userland. Since iPad 2 and iPhone 4S has the same A5 process, expect a jailbreak for both devices running iOS 5. The following is a short demo of iPad 2 jailbreak on iOS 5, we can see such as the Photo Booth, Newspapers, magazines and other system components to run properly, Cydia can also work. posted by Musclenerd:
Here’s a short video of current JB working on iPad2: http://youtu.be/oJVGl1eRW2A (Just like iPhone4S, lots of hurdles remain, no ETAs)
There is still the possibility of the Untethered jailbreak iPad 2 and iPhone 4S, so once officially release it will be the untether.
