Go easy on me because it's my first post. I mapped out a route on the Maps app on my ipod touch 2g and was driving. Very funny thing happened. A blue dot appeared along the path and followed me as I was driving along the route. I know that it followed me because I went on a wrong road and the blue dot followed me on the Maps app to the wrong road. Now, I am absolutely sure there was no wifi connection (it was a 12 mile route and I do not have wifi in my car and was driving next to rural areas). Considering that my ipod touch 2g had absolutely no connection to a data source, isn't the only possible explanation for the blue dot trailing me around the Maps route that there is a GPS in the ipod touch? I'm pretty sure the accelerometer is not good enough to track my exact location as I'm moving along. Thoughts? Anybody have similar or dissimilar experiences?
