Sn0wbreeze 2.5 is now available for Windows users to fully jailbreak iOS 4.3.1 untethered running on iPhone 4, 3GS, iPad (1st-gen) and iPod touch. Just like the new PwnageTool 4.3 for Mac, Sn0wbreeze 2.5 for Windows also uses the same new untether exploit to jailbreak all devices (except for iPad 2 ) on the latest iOS 4.3.1 firmware, and at the same time will help retain the old baseband for iPhone 4 and 3GS users so that they can be unlocked using Ultrasn0w.
