Seas0nPass is a new jailbreak utility designed specifically for the second generation Apple TV (2010). It's comparable to utilities like PwnageTool. I've used both and I personally find Seas0nPass to make the process much simpler when it comes to the Apple TV. Not only does it jailbreak 4.1.1 (4.2.1), it offers a pretty easy tethered boot mode as well. Hit the jump for a walkthrough on how to jailbreak the Apple TV 2 using Seas0nPass.
