I'm somewhat unfamiliar with the droid incredible's GPS features. I know it uses A-GPS, but I've been led to believe that the use of cell towers is only to facilitate the acquisition of the almanac or when GPS signal is unavaible altogether. I'd like to use my phone's GPS while camping, at which point I'll be well away from cell coverage. Will I still be able to get a GPS signal. If so can anyone reccomend a topographic mapping software that I can download maps from to my phone?
