New S710 Shows AT&T and not T-Mobile

[mcanavan]

I have a new S710 with a T-Mobile sim but it does not show the network as T_Mobile. It displays AT&T instead. On some of my other phones I changed the radio rom and it corrected this. Is there anything that can be done to correct this.

Thanks

because it roams on Cingular network (former AT&T, now is at&t).
it is right. Many areas T-mobile and new at&t (Cingular) share network

Well I guess I'm lucky that mine doesn't show AT&T on my new Vox. What it does show instead of T-Mobile is Get More... No matter what I've tried it always says Get More... If I go in and manually search for a network it'll show T-Mobile and Cingular as available networks. Selecting T-Mobile results in "Get More..." on the display. It doesn't bother me "too" much, and I think it's rather funny, but it is annoying that I can't figure out how to change it.
