Mail a Buddy, lets you look up a location of choice using Google Maps on your iPhone. Once you have chosen a location of youre liking, you can then tap on the email: location to a RouteBuddy friend at the bottom of screen, to then send that location via email to your friends. The email its self adds a RouteBuddy URL link in the body of the mail, so that it lets the receiver of that email view the very same location with in RouteBuddy on their Mac.
In summery this is a cool way of sharing locations on the move, with your friends that use RouteBuddy on their Macs, by harnessing the power of the Web on your iPhone. Note: the receiver of the email, must have RouteBuddy installed on their Mac.
