You must be aware that the new Apple TV runs on the new iOS 4.1 that makes it technically jailbreakable. In fact, the iPhone Dev Team, whose Greenpois0n jailbreak tool with SHAtter exploit was supposed to release yesterday (and whose release has now been postponed) had revealed that their upcoming Greenpois0n tool should be capable of jailbreaking the Apple TV as well.
Well, it looks like GeoHot had overtaken the Dev Team on this one as well. In a recent blog post, George Hotz has noted that his newly released Limera1n application should be able to jailbreak the new Apple TV. Hotz wrote,
“AppleTV is technically supported, but there’s no apps yet”
Interestingly, Erica Sadun from TUAW has also confirmed that she was able to use the Limera1n exploit to get her Apple TV into DFU mode. She writes,
” I can confirm that I put my ATV2 into DFU mode and was able to “jailbreak” it. But since no AFC services or OpenSSH were installed (let alone APT), there’s nothing that really can be done with it at this time.”
