You will collect points for logged wifi and cell sites much like Windows Mobile users have been able to do for a couple of years now.. 10000 points earns you $15.00.
I collect around a 1000 points per day (around 30,000 per month), but the top users are collecting 100,000+ points per month.
It will not work with CDMA handsets.
Once signed up visit Android Market on your device and download Navimote. In settings you can input your username and password.
