This has been touched upon in a few places, but in the US it is now required by law that all new cell phones have a GPS system installed. There are at least two reasons:
1) when you call an emengency number, they can locate you in case you don't know just where you are so they can help you, and...
2) when you are a criminal, they can locate you so they can catch you.
However, I do not know if your location is availible any time the phone is on, or if you must be making a call.
