ultrasn0w 1.2.2 available in Cydia, is compatible with iOS 4.3.2

Along with the new one PwnageTool 4.3.2, the Dev Team has also released version 1.2.2 of ultrasn0w which is compatible with iOS 4.3.2. Using this new version of ultrasn0w you will be able to unlock ONLY the old basebands, so you will not be able to decode any new basebands. You can only decode basebands from iOS 4.0/4.0.1/4.0.2 (and earlier) and iPad baseband with this version of ultrasn0w, no baseband from iOS 4.1 or higher can be decoded so don't try.

If you have installed ultrasn0w fixer for iOS 4.3.2 from Cydia then I recommend you to uninstall it and install this new version of ultrasn0w updated by the Dev Team.
