I just got my new phone off of ebay that was "Gauranteed to work for T-mobile." and it has a fuckin' cingular emblem on it!! Someone help!! imei:010495008990046 P.S Live in the USA. Muchos Grasias
have you tried your sims card to see if it was unlocked. It will still say cingular on the screen even with a t mobile card in place.
you have to have your own sims card for t mobile. An unlocked phone will still say who it was branded to but will work with any card
