Get ready folks, because iH8Sn0w has just released Sn0wBreeze 2.2, the iOS 4.2.1 untethered jailbreak which preserves the iPhone baseband so that you may unlock your iPhone 4, iPhone 3GS or iPhone 3G using UltraSn0w. Unlike PwnageTool, which is only available to Mac users (as of now), Sn0wbreeze is available for Windows as well for those of you who are Windows users. So if you want to jailbreak your iPhone 4, iPhoen 3GS or iPhone 3G and have it untethered, look no further, because here is your solution to your problem.
