    sim cards for unloced iphone4
    I am having a small problem finding out what sim cards will work with an unlocked Iphone4 in the US. Is there other than T-Mobile? and are there any that the minutes dont expire if not used each month. Thanks so much for your help.

    Welcome to the Mac Forums.

    If your unlocked iPhone is a GSM model then T-Mobile and the AT&T SIM cards will work. Note, however, that if you use T-Mobile you will be unable to go 3G as their frequencies are different. For GSM and 3G, AT&T is the only choice. AT&T used to have a contract that allowed carry over of used minutes from month to month. I don't know if that's still true. You would have to contact their customer service or go to their web page to find out.
