Now this is a new twist on using the GPS in your BlackBerry. MyMileageGenie from Converge Wireless lets you track your work mileage using the GPS built into your BlackBerry. You simply tell it when to start and stop tracking and it logs all the information to your BlackBerry. Then once a month you can email yourself the information.
Pretty cool if you find yourself logging the mileage for work every day. I can see this being more useful for companies to deploy to their workers over BES. Still the high $59.95 price tag will deter most people from this application.
