Is that the only andriod phone that comes with a built in GPS for free?
As far as I know, all Android phones have a GPS currently except the G1 from Tmobile (I think). But what I think you mean is the navigation app with turn by turn voice guided directions? If so, any Android phone running version 2.0 or higher will do that. It is a function of the Maps application and version of operating system, not the phone.
