Google Latitude

Google Latitude is a wonderful program. By using Google Latitude you are able to post your location in near real time as well as view the location of your friends. I personally own a Blackberry Storm and have used this program on a number of occasions. For those of you who may be afraid of sharing your location rest assured that you can stop sharing at any time. There is also a feature that you can share only the city you're in with select friends. Google Latitude also has all the features of Google Maps.
