Does the Wi-Fi have GPS? Because it gives me my exact address in the maps application when I am at home and the exact address when I am at my parents... I thought ok it's the internet connection location thing but then I drove down the road and it gave me my exact location on the road. Granted when I got any further Maps couldn't load anything due to no connection to the internet but it still placed me on the map. I just thought only the 3G had actual GPS like the iPhone does.
