What is GSM cellular phone carriers in the United States have paid?

I have a prepaid GSM network and use so that I can hack 3G iPhone for use with any payment that I receive, now Verizon will not work because it is not a GSM. only 10 points!

AT & T to T-Mobile TracPhone These are three GSM networks in the United States are the first two AT & T and T-Mobile.

Turn your iPod touch in to an iPhone – that actually uses the mobile phone network!
