Unfortunately, there are two problems with gps  phones. The first is 
that it doesn't work indoors.  There are folks working on that, but 
don't plan on solutions real soon.  The other problem is that its not 
accurate enough unless you use some kind of assisted gps.  In the u.s., 
the WAAS system will probably work in a lot of places.  Mobile carriers 
who use gps provide assisted gps to get the required accuracy.
