tmobile using cingular system
I don't know but you could check their website for further assistance.
And why would Cingular let them? That's one big advantage Cingular has over T-Mobile, it'd be stupid to allow them to. Ya know, they're trying to compete, not go hand in hand. 😉

all the new phones have 850-900 frequ.
probobly because the manufacturers are making them that way. i know for fact that some of the phones they carry that use 850 are only carried by them because the reception on 850 is so poor that Cingular wouldn't certify it.
As far as the 900 mhz frequency goes, that's not even used in the United States, it's only for overseas.
