Re: Unlock At&t Galaxy S3 for T-Mobile??
Theres a thread in the general section on how to sim unlock all galaxy S3's and the galaxy note.
I would recommend selling your AT&T S3 and buying the tmobile S3... That way you don't have to put up with 2g (edge)... You might be able to get 3g if your in an area that has been reformed.
