[pct-l] smartphone as GPS

[James F. Miller]

I'm looking to get a Droid or Blackberry phone for use on the trail next year. Some of these have GPS's. 
 
I'm wondering if PCT waypoints could be loaded into one of these for use in navigating the trail..like in the high country with snow covered trail.
 
One of these phones could work as all that is needed for photos and journaling and hopefully navigation in tricky parts
 
Thanks
