Although jailbreaking is most known for the enhancements it adds to portable iOS devices, namely the iPod touch, the iPhone and the iPad, it’s also possible to jailbreak the Apple TV and add several interesting new features using an application known as Seas0nPass, which has now been updated to support the newly-released iOS 4.3 for the Apple TV 2G.

Earlier today, Apple released a new software update for the second-generation Apple TV to fix various bugs, and to add some improvements over the last release.

Seas0nPass jailbreak tool has for both Windows and Mac has been updated with the latest untethered exploit to untether the jailbreak on second generation Apple TV, running on the latest iOS 4.3.1 (4.2.1)

That’s right ! Seas0nPass jailbreak tool has been updated to add support for jailbreaking the recently released iOS 4.3 for Apple TV (second-gen). Like almost all jailbreaks for iOS 4.3, this version of Seas0nPass jailbreak is also limited to tethered-boot for now.

The FireCore team has released an updated version of Seas0nPass jailbreak tool which can jailbreak Apple TV 2G untethered on iOS 4.2.1. This new version incorporates the latest kernel based exploit from GreenPois0n to untether jailbreak on iOS 4.2.1.

Chronic Dev Team has finally released GreenPois0n RC6 which brings full support for untethered iOS 4.2.1 jailbreak on Apple TV 2G. Everything else remains the same. If you have already jailbroken your iPhone, iPad or iPod touch with GreenPois0n RC5, there is no need to re-run the jailbreak.

Owners of the 2nd generation Apple TV on iOS 4.2.1 will soon be able to jailbreak their devices, untethered thanks to the upcoming GreenPois0n RC6. Joshua Hill of the Chronic Dev Team confirmed it earlier today.

FireCore team has come up with a PwnageTool like program to build custom jailbroken .ipsw files for your second-gen Apple TV. Like almost all jailbreaks for iOS 4.2.1, Seas0nPass jailbreak is also limited to tethered-boot for now.

Brandon Holland has come up with a VNC Server plugin for the second-gen Apple TV which will allow you to remotely access your Apple TV from any VNC client, running on your PC or Mac.

After releasing PwnageTool 4.1.1 yesterday, the iPhone Dev Team today has silently updated PwnageTool to 4.1.2 to fix jailbreaking issues for OS X 1.5.x Leopard users. Again, as far as the jailbreak, compatibility and the exploit is concerned, this release offers nothing new except for this bug fix.

The first third party app for Apple TV 2G, NitoTV is now available for download. It currently offers Weather and RSS functionality but the developers have promised more features in the next version.
