FireCore’s Seas0nPass has been updated to provide a tethered jailbreak for Apple TV 2 5.0.1 (iOS 5.1.1). Tethered jailbreak means that every time there is a need to reboot your Apple TV, you will have to connect it to a computer. Functionally, both tethered and untethered jailbreak are identical.
FireCore’s Seas0nPass jailbreaking tool has been updated for Apple TV 2 running latest firmware 5.0. It’s still a tethered jailbreak, meaning every time there is a need to reboot your Apple TV, you will have to connect it to a computer. XBMC, Plex, Remote HD, Rowmote and Overflow plugins are not yet working on AppleTV 5.0. Media Player, Couch Surfer, nitoTV, Last.fm, Weather, RSS Feeds and Maintenance are already supported. Non-working items require an author update for 5.0 compatibility.
