Navizon uses cell phone towers to pinpoint your location (within a few hundred yards) and is able to push those coordinates to the Google Maps application. The result? Free GPS(ish) functionality on the iPhone.[…] Thanks to cambrown99 for providing this nice story on Digg.
What other users say about this:
dfbills: Navizon displayed my location within 30 feet of accuracy in NYC. wow.
JoeBaynham: Cool but will it work global? Hence Global Positioning System.
