Certainly iPhone 3Gs and iPad will work much better (more accurate quicker updates) because it has a magnetic compass, but for iPhone 3G course up will use COG (Course Over Ground). I have found on iPhone 3G that COG doesn't become reliable until SOG is above about 5 knots. Also make sure HPE (Horizontal Position Error) displayed in the "Instruments" tab is less than 50'.
