Cingular band on unlocked phone - true coverage?
I'm a T-M customer and frustrated with weak signals. I bought an umlocked phone and it virtually always shows "Cingular" instead of "T-M" of the screen. Two related questions ...
1. Does this mean that I'm really using the Cingular network/towers?
2. If I force the phone to use Cingular, am I getting the exact coverage I could expect should I switch?
Another question ...
What is the stste of the two GSM carriers in terms of network ownership/leasing? Are the two networks virtually identical, as I'd heard a while ago?
