An update to the ultrasn0w unlocking tool that will fix bugs with the latest version of iOS is nearly ready to go public. Dev-Team member MuscleNerd revealed on Twitter yesterday that all issues with the 4.3.1 firmware are now fixed, and that the unlock will be go live after some testing.
The new version of ultrasn0w will not unlock new basebands, however – it’s purely for users that have already performed the hack on their device and wish to retain the unlock when they update to iOS 4.3.1.
When it’s ready, ultrasn0w will be available to download through Cydia. Users updating to 4.3.1 will need to use the latest version of PwnageTool (Mac) or Sn0wBreeze (Windows) to preserve their baseband.
