iH8sn0w's popular jailbreak tool for Windows, Sn0wBreeze, has been updated with support for an untethered iOS 5 jailbreak on the iPhone 3GS. iOS 5 is still in the Beta 1 stage, and Sn0wBreeze Beta 2 is the first method available for an untethered iOS 5 jailbreak on the iPhone 3GS.
Thanks to the old bootrom on the 3GS, users can enjoy a fully untethered iOS 5 Beta 1 jailbreak with the newly released Sn0wBreeze update.
