FireCore team has just updated the official blog regarding Seas0nPass jailbreak for Apple TV 2G running iOS 4.2.1 Windows version.
Seas0nPass for Windows is now available for beta testers. The public version will be available by the next week.
For who don't know, Seas0nPass is a jailbreak tool for Apple TV 2G and it looks like PwnageTool jailbreak, Seas0nPass is only available for Mac till now but it still tethered jailbreak, so the team is waiting for Greenpois0n RC6 which will bring untethered jailbreak for Apple TV 2G running iOS 4.2.1 to update Seas0nPass to become untethered jailbreak for both Mac and Windows. Stay tuned.
