And here it comes, another untethered jailbreak for Apple TV 2 on iOS 4.3.1. Snowbreeze has been updated to version 2.5 and can now jailbreak your atv2 on the newest 4.2.1 software. Sn0wbreeze is considered as the unofficial PwnageTool for Windows. It works with Windows XP, Vista, 7 and can be downloaded from here. A tutorial on how to jailbreak Apple TV 2 on iOS 4.3.1 using Sn0wbreeze 2.5 will be posted shortly.

Update: As you all noticed, Sn0wbreeze 2.5 didn’t really bring the support for Apple TV 2; for the last two days we’ve been trying hard to jailbreak our atv2 on the latest 4.2.1 firmware (iOS 4.3) using Sn0wbreez but we didn’t succeed (famous error 14). Good news is that the software has just been updated to version 2.5.1., which is said to provide “full Apple TV 2 support”. DFU instructions for atv have also been added. You can download Sn0wbreez 2.5.1 from ih8sn0w website and give it a try.
