Hey folks we reported before that a new Jailbreak was launched by Firecore which was called SeasonPass. The tool is used to Jailbreak your Apple TV2G on firmware 4.2.1. For those who are unaware, seas0npass is a jailbreak tool specifically designed for Apple TV. It is similar to PwnageTool for Mac which helps you to cook custom IPSW file. Later you can restore this custom IPSW file via iTunes to jailbreak Apple TV 2G.

Seas0nPass 0.6.6 includes ‘tethered boot’ option for Apple TV. This new version fixes the problem with Wi-Fi networking.

you can follow the complete guide here on how to perform this jailbreak and how to do a tethered boot. And this is only for MAC till now and no announcements are being made on when the Windows version will be launched.
