About location services
Use your phone to find out where you are. There are two methods: GPS and wireless
networks. Enable the wireless networks option if you only need your approximate
location, and want it fast. If you want a more exact position, and have a clear view of
the sky, enable the GPS option. In situations where the wireless network connection is
weak, you should enable both options to ensure that your location is found.
