Restarted the project and made it available for a new tracker!
GG-Tracker now gets its positions from CellDB.org if no location of the GSM CellID can be found in its own database.
Added statistical data like topspeeds, distance from home and GSM antennas.
Only a few minor fixes, no bugs, just to get a better positioning without the GPS connected.
It's out there, it works and I can not find any bugs anymore. It's live at http://gg-tracker.eppenga.com if you like to see it first before installing.
