It's not just the GPS function on the phone that is used for this kind of tracking. As long as your phone is turned on it is constantly communicating with the nearest cell tower or two (or three if you're in the righ places) and those towers are relaying that location infomration back to a central switching office so the system knows what tower to send your incomming calls to when someone calls you.
I have used this tracking information to help find runaway kids, a drug dealer/murder suspect, and my own phone when I left it somewhere. Darn useful little feature.

I thought there was an option on the cell phone whether to leave GPS enabled or not.
Cool.
On some phones you can "turn it off." However, it's not really off just supposed to be denied to anyone but law enforcement.
