Looking for a GPS app that will let me download maps and save them on my droid. That way if I'm ever in a place (like the mountains) where I don't have cell signal, my GPS can still function. Or if I want to use less data, I could download a map of the city I live in, so that the map was already there. Hopefully that makes sense. I remember seeing something like this for the blackberry curve but that was a couple years ago and that phone was not nearly as awesome as the droid. Thanks!
