I'm looking for a GPS program that will store maps on my phone for use when the signal is too weak to download maps over the internet.

I've been using Google Maps for a while because I use both the map view and overhead images, but when I'm doing work I don't always have the signal strangth required to refresh the maps. However, I still have a GPS lock.

What program has pretty good maps that would fit what I need?
