So even with offline GPS I would still need the 3g version?
I own a Nokia 5800 Nav Edition that has all the map data downloaded on the phone. I am guessing this is not possible with the iPad or iPhone?
None of the ipad versions have the true gps/sat tracking hardware built into them. The 3g version uses cell signal to triangulate your position (which isnt extremely accurate or fast) - even though it will work, its more of a gimmick - compared to good gps units. (try using ipad as your main gps in any downtown if you dont believe me!)
