I just heard some rumors about the TopoExplorer GPS application which is still in beta test on its
website. This seems just to be "officially" because I downloaded it and the beta is expired already. So I was diggin a bit more on the web and found out that the final version will be released soon.
I could gather the following (unconfirmed) details:- TopoExplorer for BlackBerry will be available as free download
- It comes with a free set of map packs
- Additional more detailed map packs can purchased
- Additional map pack coverage for the first tier will be: California and Florida
- Map packs for the US will have a scale of 1:24,000 (or 7.5 minute)
- Map packs can be installed on the sd card
- TopoExplorer does not need any internet connection for map navigation
- Additional map packs can be purchased as "download" or "dvd pack"
- TopoExplorer works with internal / buit-in GPS or external / Bluetooth GPS
