If you're running a RAPH800, IT'S NOT GPS!!!! (Not yet, at least...)
The first post goes over this (well, maybe it's the 2nd or 3rd... but still!) it's cell tower triangulation. GPS is working for certain devices, but evidently our phones don't dump the NMEA data that the devs are using to feed to Android. The devices that provide this raw NMEA data are working, RAPH110, RHOD400, etc. Hopefully they'll sort out a way to parse the data that they are receiving from our devices, and get GPS working for our devices as well
