Probably not. But GPS is not the only way you can determine where you are. Imagine this: a "stumbler" where you say "I'm at Cockfosters on the Picadilly Line of the London underground, stationary." The app knows the Picadilly Line, and the stations on it. It stumbles the wireless environment as you go along. Each time you hit a station, you press a "At Station" button (so it's not fooled by stops in between stations). Then, next time someone travels that route, the phone can use the recorded wireless data to tell you what station you are at, as long as there is _some_ signal available. (E.g. London Underground how has wifi on many station platforms.) You don't need GPS.
