Can we get the Maps.app from the iPhone firmware and put it into a iPod Touch Jailbreked???
 
I thought it would have been nice to have, but not very useful given the rarity of free WiFi across my town. Yet the University I teach at has WiFi everywhere, and Google street view has all the buildings on it. I often am stopped by visitors to the campus who are lost. Being able to show them a map, directions, and a view of the building they are headed for would have been a neat trick.
