Most of these apps are primary for urban navigation. I do a lot of trail riding where cell coverage is spotty at best. What I am looking for is an app I can pre-load maps in with way-point tracking. I used trimble with my Razr which was pretty good, but to my knowledge not available to win-mobile customers. Another of interest is being talked about here.....
