it's not really a good idea to fix it that way.
gpsfix is the flag to store the current gps status, and we should not falsify
this state just for a gui fix. other functions may rely on that...

sorry, I meant 4, not 3.
my experience with gps devices is, that there was always a 3d fix, when I had 
dgps available. but if that's not inevitably the case, your way may be
