So I've already jailbroke my iPhone and now I'm trying to unlock it. I have an AT&T sim card that I need to use for the unlocking process. I also got my tmobile micro sim today and it's working and everything. I've followed every step. But in the end when it comes to actually finish to unlock it doesn't want to accept my tmobile sim card. Can someone help please? I'm so confused and pissed.
