i HAVE CINGULAR tdma and it out performs my wifes cingular gsm. why is it i hear that cingular 's gsm in northern nj. is carried by voicestream???? so where is cingular in this picture. and why are they useing another newtwork's towers and not their own. also why does tdma pick up better than gsm. i thought gsm was supposed to be better. i think that this is horrible if all the tdma companies want to go gsm. there is bearly and reception when you enter a building or a house or an over pass.
