Cell Phone Knows Where You Are
This is awesome! Google Maps for Mobile can now display your location on and via your cell phone. Google uses cell phone towers to ping your mobile phone. A blue dot appears on the map, marking your location if you have GPS on your phone. If you don't have GPS, a blue circle appears on the map, representing your approximate location. It's like having a gigantic fleet of satellites, all tracking where you are. Never taking an eye off of you. Always watching.
