I have a Nokia 8260 which I had with AT&T, I recently switched my Cingular number to this phone, it works but the screen still says AT&T, is there a way to change this because I dont know if it's roaming or not .
I'll appreciate any help on this because I am pager tech but new at cell phones.
BTW I called Cingular about this and they say the phone should'nt even be working.

Thanks
