Where I live and work around Albany, NY, "My Location" in the Maps application can tell me which end of a building I'm in. Last weekend I traveled to RI and every time I asked for directions, the Droid told me it was searching for a GPS signal. My wife's Magellan navigator was a little slow to lock on but got us where we were going. When I got home, my Droid knew just where I was. Why would GPS reception vary so much? Doesn't the "G" in "GPS" stand for "global"?
