The FireCore development team recently tweeted that Seas0nPass has been updated using Comex’s Saffron exploit (Jailbreakme 3.0) to Jailbreak the Apple TV 2G untethered running the iOS 4.3 (8F455) firmware. The best aspect to this Jailbreak is that it is an untethered Jailbreak. Meaning you can reboot your Apple TV 2G without having to first run Seas0nPass for a ‘tethered boot’.
Note: aTV Flash (black) beta6 is compatible with the new iOS 4.3 (8F455) firmware. This new version of Seas0nPass also includes Media Player 0.7.1.
We will have a how to guide on Jailbreaking your Apple TV 2G running the iOS 4.3 firmware available shortly. In the mean time you can download Seas0nPass from the iJailbreak Downloads Section. Additionally you can use one of the download mirrors below:
