I am not at all an expert on GPS. But, I read not long ago that some of the electronic devices use not only GPS, but signals from the phone towers to supply your location. I would like to know more, for sure.

I think it is google that sent me an email showing everywhere I went in the last year, including date and time. Big brother is already here.
