Just got a Nexus S and so far so good. I am not clear though, about a feature of the phone so I will need your help. I used to own a Nokia N97Mini and that phone had a built in satelite receiver for GPS. You could use it without using any data from your carrier, just using the built in receiver. The Nexus S has this feature or it just uses the GMaps along with the cell network.
It is kind of importand because in Canada they gouge us on the data plan rates.

Thank you
