Trying to get a good Topo Map app for my blackberry 9650 that is low cost(possibly free) and works better than mapmyride. I do quite a bit of hiking and stuff so it would be very useful for me....and prob an extended batter as well lol....
Try blackberry.com or the BlackBerry App World they have some there but I haven't tried them only because I haven't had the use for one but if I was looking to buy, it would be there or the CrackBerry App Store. The only 2 App Stores I trust so far!
