For on-line vehicle tracking I wrote a little daemon to run on my 
OpenMoko FreeRunner phone; it gets position from gpsd and forward 
it to a remote database server using UDP packets over GPRS 

It works very well, it seems also that GPRS modem does some 
buffering when switching from cell to cell, because I exprience 
very few data loss also away from cities. I send a position every 
10 seconds, I lost max 3% of packets here in Italy.

The UDP connection is "send and forget", no retry is made. An 
improvement of the software can be some sort of acknowlegment and 
packet retransmission.

Here you can find that experiment:
