hi guys, I bought an iphone 3gs (3.1.2 (7d11) ; 05.11.07) . It was simlocked. I jailbreaked and unlocked it. But whenever i turn it off or reboot my iphone , it gets locked again. So i need to unlock it after every reboot using blackrain. People say that the new series of iphones can only be unlocked temporarly. Do you know how to make it permanent ? I'm bored of unlocking it ????
