1. I have ZiPhone, I know how to jailbreak but I kinda want to unlock. I'm with AT&T, I just want to unlock just in case. How can I do this with ZiPhone?
2. I jailbroke my iPhone and I use MIM and I changed the carrier name. I want to go back, but I recently restored my iPhone. Then I just jailbroke again and downloaded MIM so I can revert, but I open MIM and it just closes after a white screen. What am I doing wrong?
Please everyone, it would help me a lot if you guys could help me.
And thank you in advance.
