HI yes you can use your t-mobile sim in phone locked with cingular only after unlocking it ..You can easily unlock your phone using sites like TheUnlockArena.com here they are rendering unlock code for all mobile models at reliable cost ..You first verify that whether they are rendering code for your mobile model .If yes then pay for it and unlock your phone ...
