Google Maps on iPhone 3G

Google maps comes with all new iPhone's. I really got to use it this last time I was out of town and was very impressed. Especially with the GPS feature. I was traveling with by business partner who has a Blackberry and was comparing the GPS features. Now from the beginning the Blackberry seemed to be much better. But after a couple tries, we started to notice that Google Maps was sending us on a better route most of the time. Now, the Blackberry might have been sending us on a shorter route, but for the most part, the iPhone sent us on streets that made a whole lot more sense. Blackberry's GPS was constantly sending us down streets with a speed limit of 20 MPH and lots of stop signs. The iPhone or Google Maps, was sending us on routes that were much quicker and driver friendly. I can't speak for all users of both GPS systems, but during my last trip, the iPhone consistently outperformed the Blackberry.
