Cingular Network with or without A-GPS service.
Note: (Most phones with "GPS" in fact use A-GPS technology. The "A" stands for assisted, and means that the phone relies on the network for help in determining location. Although the phone does receive GPS signals directly from the satellites, it can't determine actual location without help from the cell network.)
