If you have a 7100G, it could be from Cellular One, Cincinnati Bell, Cingular, Dobson, or SunCom. If your Cingular SIM doesn't work in it, then it is probably one of the others and the phone is not unlocked.
The question, then, would be, where did you get the phone and why do you not know to what network it is locked?
