Does this work even when you don't have AT&T service (due to being out of range/in mountains/under tree canapy/etc..)? I ask becuase I tried to use iPhone maps while on Oregon coast a few months ago & my rental car had GPS. Well the rental car GPS worked fine the entire time but my iPhone didn't work 1/2 the time due to no AT&T service... Yes, I have the 3G iPhone.
