Blackberry Bold GPS

I'd like a java midlet for my blackberry bold that does the following:- - tracks my GPS position when I press start speed in km per hour distance travelled - when press stop the GPS information is saved to a file that can be accessed on my pc The information I want in the fil is the GPS time stamped data. I do not have a specific preference for the format of the data. It could be XML, CSV etc as long as I can import it into Microsoft Excel.
