Me and the missus had major problems last month when we were traveling around Africa. When we were in the bush, no signal = no GPS... I didn't take my normal unit along thinking
No problem, iPhone is "Magical" ... WRONG!
My missus has an iPhone 3GS

I think this is only true for the inbuilt maps program or other map services the require data connection to retrieve maps. I've used my iphone with no signal using other apps. The phone just uses the GPS to acquire long/lat, the app must do the rest. It can also use network info if required.
So if you have good programs you don't need data access. Thats why the garmin/tomtom apps for iphone cost so much - they include a full download of maps and don't require a 3g data connection. But if you just want a long/lat read out there are many free apps around.
