[pct-l] smartphone as GPS

[Austin Williams]

Be careful.  Most of the time the 'GPS' in smart phones is based on
cell-tower triangulation, NOT gps-satellite triangulation.  That means when
there are now cell towers around, the "GPS" on the phone won't work.  Make
sure you buy one that uses *real* gps, not the kind that uses cell tower
triangulation.

Just a heads up.
