iH8sn0w has just released Sn0wbreeze 2.5 which can now jailbreak iOS 4.3.1 untethered on all supported iDevices except iPad 2. With Sn0wbreeze 2.5, you can create iOS 4.3.1 custom IPSW for your iPhone which on restore through iTunes will not only jailbreak it but will also preserve its current baseband. Just like PwnageTool 4.3 and Redsn0w 0.9.6RC9, Sn0wbreeze 2.5 is also based on Stefan Esser's (@i0n1c) untethered exploit.
