No. It's locked to Sprint and cannot be unlocked to domestic US gsm use.


wait, theres unlocks out there for international GSM use

but how come it can be used GSM outside the USA but no in the USA? that makes 0 sense
 
Find an at&t iphone 5 and unlock it and you will be able to use it on tmobile, and you probably won't get any 3g service.
 
I believe the Verizon iPhone 5 can be used on t-mobile since Verizon isn't allowed to lock the phone per FCC block c rules.
