FYI-My Location doesnt use GPS alone. It uses cell towers too. My guess=This is why if you open Google Maps it'll have your location with 1600 meters until it gets a GPS lock after you go under Menu and select Use GPS. Just FYI.
From Google:
"We'd be happy to lift the covers and give you a peek into the inner workings of the Google location server, which powers the My Location feature.
Wireless phones can make and receive calls because they are connected over the air to a nearby cell tower. The phone knows the ID of the cell tower that it's currently using. If the phone has GPS, the Maps application on the phone sends the GPS coordinates along with the cell ID to the Google location server. Over millions of such updates, across multiple phones, carriers, and times, the server clusters the GPS updates corresponding to a particular cell ID to find their rough center. So when a phone without GPS needs its own location, the application on the phone queries the Google location server with the cell tower ID to translate that into a geographic location, i.e., lat/long coordinates. Nifty, huh? We think so."
So now my question is-if our phone DOES have a GPS chip does that factor into My Location? I dont think so, I think I've read that the service is Tower based. Could be wrong. AGPS has no effect on My Location for me, On or Off it works the same.
