so we were just driving around and i decided to mess with my ipod touch. i open up the Maps app (im on 2.0 mind you) and hit "Locate Me" it pops up with a dialog with all the wifi networks around me, 2 show up, both of which are locked. so im not connected to the internet in any way. i hit "Cancel" on the wifi network screen and it tells me that if i dont want to be notified then turn off the setting blah blah, so i hit Ok. after this, the blue locate me circle shows up in Maps, zooms in, and guess what. pinpoints my exact location. i wasnt even online, yet it found me. i left it on locate mode, where it keeps scanning and scannin until you turn it off. we were driving, and to my surprise, every half-block we went, the blue circle would move half a block in the direction we were travelling! my question is: how in the hell does it know where i am if im not even connected to wifi?!
