Applenberry has released GEVEY Ultra to unlock iPhone 4 on IOS 5.1 or lower basebands 1.59,2.10,3.10.1,4.10.1,4.11.08,4.12.01. If you are searching for free unlocking solution,currently there is tethered jailbreak for IOS 5.1 and utransow,but it does not work on most of the basebands supported by GEVERY SIM. Before purchasing GEVEY Ultra ,i recommend you to check the free unlocking solution using SAM which unlock all basebands.
