The so-called 'GPS' is actually A-GPS from the locations of the Wifi hotspots collected by Google or obtained by triangulation of the GSM posts in case of 3G.

Your iPad must have been WiFi only, or your understanding slightly wrong. It definitely seems Shane's research is correct.
I regularly use my 3G iPad in remote areas (with no 3G or WiFi connectivity), using apps with pre-downloaded maps and GPS for tracking on those maps. It matches the car GPS just fine and with good accuracy.
