Uhm, sorry, you just provided mis-information. My Evo 4g works off of wifi, 4g, 3g, and I can still get coordinates with GPS turned off. They base
it off your IP, then, careful redundancy in the system.
My phone has backup ways to get coordinates if GPS fails. In fact, GPS eats up battery life, and I don't like TPTB tracking me. I turn it on when I
am going to visit friends, so my wife can monitor my location if she had to.
I locked into 4-7 GPS satellites during the course of previous tests.
Then I turned GPS off, and wifi on. I got the same coordinates to within a few arc-seconds. The compass app in smartphones has several ways to
determine location, and the tricorder app is simply awesome. Don't knock em until you get one and play with it. You'll almost give up your laptop,
except for typing.
The compass app is not dependent on GPS, it is based upon the built-in magnetometer, and works fine with GPS or not.
Smartphones are little bundles of fascinating tech, the tech being 5 years ahead of programming. Thankfully, it's android this time around. We are
striving to catch up!
