Earlier today, the iPhone Dev Team finally released Redsn0w 0.9.6rc9 for Windows and PwnageTool 4.3 for Mac to jailbreak iOS 4.3.1 untethered for iPhone, iPad and iPod touch. Now, iH8sn0w has released Sn0wbreeze 2.5 for jailbreaking iOS 4.3.1 untethered on Apple TV 2, iPhone, iPad and iPod touch. As previously reported, this will not work on the iPad 2. Sn0wbreeze is considered to be the unofficial PwnageTool for Windows as it preserves your old iPhone baseband. However, the iPhone Dev Team is working on an ultrasn0w update for iOS 4.3.1 unlock and we'll let you know once that comes out.
A detailed tutorial on how to jailbreak iOS 4.3.1 untethered on Apple TV 2, iPhone, iPad and iPod touch using Sn0wbreeze 2.5 will be posted up shortly.
