Ok my buddy gave me his old Tmobile S3 in White. I would like to be able to switch between my Iphone 5 and this. I have ordered a Nano to Micro sim adapter. I am not sure if the phone is locked but I am guessing I wil find out once I slip my sim card in it. If it is locked can I just us the *mod edit* site to unlock it? Has anybody used them? I have been reading that if I do run this phone unlocked on ATT that it won't run LTE. Is that true?
