I have the BB curve 8310 for att. I downloaded BB Maps it's installed but when I load it there is only a graph no streets. when I drive it will tell me how fast i'm going but not where I'm going. so my real question is if I download google maps or any other APP do I need to have a data plan for the internal GPS to work. I'm currently not on any data plan and I was looking to see if I'm able to take advantage if the internal GPS. Any help would be great thanks.
