I seem to remember that on my 5800, if I went to google, it would tell me my current location, based on triangulation of my cell towers........without using my GPS at all.

Does anyone know how this works, and is it possible to get similar functionality from the N900 (I know it has GPS built-in).

I know that the N900 has GPS built-in, but i am curious to find out how google achieved this and would like to come up with a similar thing in Maemo
