I believe both versions of the iPad have the GPS, the non-cellular (wifi-only) version just doesn't have a way to receive the signal from the satellite. I bought an external GPS unit from Bad Elf, looks like it will work very well. It can simultaneously connect to the iPad, iPhone, and my laptop via bluetooth.
