GPS (well, pseudo GPS) on iPhone
Navizon unveiled the software only positioning system for mobile phones, which works on iPhone and integrates with Google Maps on iPhone.
The software works by triangulating the GSM cell tower signals to find your location. Also, the software uses something I havent heard of before, wifi-triangulation from existing known Wi-fi access points.
The app itself is very simple, It tries to triangulate your location, and once it finds your best possible location, sends out the lat & long co-ords to GMap and launches GMap, centered on your location.
Not sure how this app, would perform while driving, where there is a constant handover from cell to cell.
for me the first attempt yielded best positioning, but after that it kinda thew me on an Interstate (I-90).
More later.
