iPhone 4S and iPad 2 are the only devices currently incompatible with the new untethered jailbreak solution

   Last night the Pod2G hacker published on his blog information that shows that iPhone 3GS/4, iPad, iPod Touch 3G/4G and Apple TV 2G were untethered jailbroken on iOS 5/5.0.1. These are all devices released up to 2011 on which iOS 5 (for Apple TV we are talking about an iOS 4.x) can be installed and only iPad2/iPhone 4S remained without compatibility. Practically now, most iDevice owners can do untethered jailbreak if the solution is released, but owners of iPad 2 and iPhone 4S tablets remain without such an option.

   Pod2G complained that he doesn't have an iPad 2 or an iPhone 4S on which to test the new untethered jailbreak solution, and until he gets hold of such devices we won't know if they can be exploited. I assume that in the next few days Pod 2G will manage to get hold of such terminals and jailbreak them, but even if it succeeds, the jailbreak solution will only be released after the publication of iOS 5.1 in iTunes. Until then, we have functional untethered jailbreak on 80% of the iDevices that can install iOS 5.
