I found this great little tool on CrackBerry the other day and finally got a chance to try it. I used it in the car on the way to work today. It kept very, very close to the mileage and speed that the car registered. So I decided to give it a try on my run tonight. Great tool instead of buying one of those overpriced GPS watches.
Now if someone can explain to me how the blackberry can track satellites while being buried in my fanny pack, that would be great.
