How to Unlock iOS 4.3.2 Using Ultrasnow 1.2.2 [Current Unlockers Only]

In addition to PwnageTool 4.3.2, today iPhone Dev Team also released Ultrasnow 1.2.2. Ultrasnow 1.2.2 can unlock up to iOS 4.3.2 provided you are already on unlockable baseband. If you are still running any older iOS version, you can now safely update your device to iOS 4.3.2 while preserving the baseband and unlock it using Ultrasn0w 1.2.2.

It is very important that you restore to custom iOS 4.3.2 while preserving the baseband so that you don’t loose the unlock ability. For this purpose you can use either Sn0wbreeze 2.6 (Windows only) or PwnageTool 4.3.2 (Mac Only) which not only preserves the baseband but also provides untethered jailbreak during building a custom iOS 4.3.2 iPSW file.
