Hi everyone, I have tried several times to unlock an Iphone 4 with IOS 4.1 and baseband 2.10.04 but I have been unsuccessful. I have tried preserving the baseband and updating to the latest IOS, but nothing. Furthermore, after jailbreaking it, I have tried installing Ulstran0w 1.2.5, but have failed. I would appreciate it if anyone can help me unlocking the iphone. Thank you in advance.
