You access the GPS system using Core Location. But don't assume it's GPS, because (a) iPod touches and early iPhones don't have GPS, and (b) if the phone is inside a building it may not be able to get a GPS fix.

You turn Core Location on and off using CLLocationManager. Use the startUpdatingLocation and stopUpdatingLocation methods to turn it on and off.
