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.

Your post was moved to the correct forum as it does not belong in the "Buy Sell Trade" forum. Please read forum descriptions and Sticky notices before posting. Thanks.
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.
