That, and Google Maps. Great application, works around the world, and the traffic updates are pretty accurate.
Uh, I think I have told you this before... and again you repeat this? One of the native apps on the iPhone since day one is Google Maps... with traffic updates as well. And exactly how much experience have you had with the User interface on the iPhone to make the judgment call that TouchFlo is more flexible and more usable? I would daresay, very little.
