Navizon is a cool company that has some great technology that takes data from your mobile device - such as cataloged WiFi access points and cell towers your phone can "see" - and then uses that data to triangulate and plot you on a map.

There's a new third-party app for the iPhone that runs Navizon and connects to their service to use the data from the iPhone, and which then feeds your location to the Google Maps app and pinpoints you. Nice. Requires the AppTap installer, of course.

Not nearly as good as something like TeleNav, but very cool and useful nonetheless. It gets you fairly close, especially where WiFi access points are used for reference. I have installed the app on my iPhone and am trying it out today. It was able to find me accurately within a city block earlier, and other times it reported there was no known data points visible to the service. At least so far all it has used is WiFi access points to get a fix, not cell towers, so there might be something I need to change or set up, not sure.

Expect their service to be a little bit overwhelmed with excited iPhone users today and in the near future, in the event you experience problems signing up for a Navizon account.
