pod2g seems to be on a roll. He has just confirmed that his untethered jailbreak also works on iOS 5.1.1.
He just tweeted:
OK, tested on an iPad 3,1 running 5.1.1. Jailbroken untethered. 🙂 No issue.
pod2g has clarified that since his untethered jailbreak works on iPhone 4 and iPad 3, it should work with other iOS 5.1 devices like iPhone 4S and iPad 2 as well. But it may not work with Apple TV 3. So the same should apply for iOS 5.1.1.
pod2g has said that it will still take him “some weeks” to release a user friendly tool for his untethered jailbreak for iOS 5.1. Until then, iPhone 4S and iPad 2 users can use the latest of Redsn0w to downgrade to iOS 5.0.1 and jailbreak their device using Absinthe jailbreak.
