We just returned from a trip up to the St Lawrence, 1000 Islands area in Canada. I brought my Verizon 3G iPad 2 loaded with MotionX GPS. We were able to connect to the Verizon network from within Canada, as long as we didn't go too far from the border. I downloaded maps of the area before we left home, so i could used the app without a connection, but since we had a connection in most places, the google satellite views were available and were incredibly helpful. It's really neat to tap one button and see a satellite view of the spot you are currently in. The GPS function was incredibly useful to us.
One point I should make is how few places we found WIFI up there. Even McDonalds didn't have WiFi. The only place I had wifi on the entire trip was in the motel, and even there I had to wait each day while they got me a new access code.
I was very happy to have the 3G feature available on this trip.
That said, we had at least one case where the GPS quit working. I rebooted the iPad and it started working again.
