According to the Dev-Team Blog, the new Apple TV can run iOS 4.1. The blog states the following: Its looking like SHAtter is going to be the gift that keeps on giving. Even though the new AppleTV isnt yet in peoples homes, the firmware is available on Apples normal public distribution servers and SHAtter has been used to decrypt its keys! The main filesystem (Mojave8M89.K66OS) key for 018-8609-066.dmg is: 31c700a852f1877c88efc05bc5c63e8c7f081c4cb28d024ed7f9b0dbc98c7e1406e499c6 This means that SHAtter found an exploit in iOS 4.1 and will possibly make the Apple TV jailbreak-able as well. This is very good news and hopefully we will see the release of the jailbreak soon.
