    Usually when someone mentions "baseband" my first thought is that the phone was jailbroken, because regular users who haven't hacked their phone don't even know what Baseband is (the word doesn't appear anywhere on the phone or in documentation). If, by chance, your phone was hacked or jailbroken the "legal" unlock won't work.

    Before going to the unlock by itunes, I restore it from factory. There was not any problems, I received the message of congratulations, your phone is unlocked, but when I try with a different sim, it just say "no sim". My baseband is not comun, is 5.15.04 it is the original, I did not modify it. I do not if there is a limit of unlocking actions, of there is a conflict in my baseband. My baseband can not be modified with jailbreaks for unlockings.


    Thanks for your fast answer Larry.
