Hello,

I have a new iPhone that I have jailbreak and unlocked. I still have the ATT iPhone sim in.

I have Sprint service and I'm not sure if my phone has a sim.

If I want to use my iPhone as a phone do I have to switch from sprint to ATT even with an unlocked iPhone or can I go and buy one of there prepaid T Mobile phone and use that sim?

Thanks

thejoe
