Got an AppleTV? Want to get your jailbreak-thang on? Here's your Seas0nPass. Seas0nPass is the Apple TV jailbreak app which allows a quick and easy jailbreak on most systems, this allows a user to install extra apps including XBox Media Center, Boxee and Plex.
Right now the jailbreak doesn't offer much - think of non-jailbreak as a brick wall, jailbreak as a door through that brick wall and right now the room is empty and dark. Soon the room will be filled with love, lollipops and the above programs.
