    I just purchased a LOCKED AT&T/Cingular iPhone. I thought that since i already had a cingular motorola razor that i would just remove the sim and place it in the iPhone. I am now learning that i may have assumed wrong. I NEED HELP. Gordon

    Maybe call AT&T up, and ask for an SIM card that works with the iPhone....

    64k Smart Chip in my Motorla

    So is it true that the 64k Smart Chip will not work in the iPhone?
