What? I don't understand what this means.
Bluetooth is a serial communication protocol. It's range is on the order of a couple of meters.
GPS is a line of sight thing. GPS signals are generally too weak to give you a decent position when you're indoors. But outdoors, even though the GPS chips in the phone's are pretty low end, you're probably getting 5-10m accuracy, it's not too difficult to get that order of accuracy. Faster acquisition times too because one of your unknown's (time) is already pretty much known from the phone (courtesy the cellular network).
