Just bought a Lumia 520 AT&T Go Phone to use as a music hub and backup phone If needed. I most likely will never use it as a phone, so I wanted to play around with flashing a different rom...specifically the New Zealand Telecom rom. Question is: If the need arises, will I still be ale to use my AT&T sim in the phone even though it is flashed wit the NZ Telecom rom.
Thanks
