There is suppose to be a new GPS program out in iTunes today. I know little about it yet, but it appears to be highly regarded. From what I do understand, it is $2.99 and uses Bing for maps. I think it is called Motion-X.
I think the trick is that the cellular connection assists to pinpoint you before the accuracy of the GPS kicks in.Better to have both. Some regions don't have 3G, some don't even have basic cell! Other places are too deep underground. But you can set up wifi anywhere. Just sayin'...Then the iPad 3G has some type of GPS hardware built into it where the WiFi only doesn't.
Just another reason for them to drop the WiFi only all together.
I just completed a 4000 mile round trip with my 3G ipad and used maps the whole way. The GPS was flawless most of the time. Had a one day glitch where it couldn't detect my location for some reason. I tried using co-pilot and for days it wouldn't even open. My AT&T navigator app that I use on my iphone, worked fine on my ipad when I tried it, but I used the google maps app 95% of the time. That was because I was the navigator while my husband was driving. If I'd been alone turn by turn with the AT&T app would have been my choice.

Want to use my ipad2 as a gps for driving directions because of large screen and light. Voice directions included would be terrific!
