Unlock iPhone 4.3.2 with UltraSn0w

Ultrasn0w 1.2.2 can unlock iPhone 4.3.2 firmware on iPhone 4 and iPhone 3GS. This UltraSn0w unlock does NOT include any new iPhone baseband sport, instead, it just fixes the iOS 4.3.2 compatibility issues.

Important

  • Compatible Basebands: 01.59.00 | 04.26.08 | 05.11.07 | 05.12.01 | 05.13.04 | 06.15.00
  • Not-Compatible Basebands: 02.10.04 | 03.10.01 | 04.10.01 | 05.14.02 | 05.15.04 (Dev-Team is working on Downgrade Baseband method)
  • iPhone 3GS (not-compatible baseband) users can upgrade to 06.15.00 baseband which is unlockable (Here is How to). Upgrading your iPhone 3GS baseband to the 06.15.00 iPad baseband hack to unlock MAY cause you to lose your GPS!
