According to the blog 2 days ago, it could handle aTV2.I know the ATV3 has some hardware blocks in place to prevent delivery of some code to it (even when iOS 5 had been jailbroken, you could not jailbreak ATV3 running iOS 5). However, I hope that this jailbreak applies to ATV2. I would very much like to upgrade my Apple TV 2 units to iOS 6 and still be able to run XBMC.
