"In a blog post, AT&T says they'll unlock any device provided certain conditions are met:"
I tried to unlock an old Iphone 3Gs over the weekend.... submitted the info on the website. Got a response...
"Thank you for contacting AT&T Customer Care about unlocking your iPhone. Please retain your Request Number for reference. In order to process your unlock request, we must receive a faxed copy of your original receipt"
Origianl receipt? I didn't hang on to that. I figured they would find a way to deny it.
