I am hoping iPhone 4 GPS is as good as iPad 3G GPS. It's a world of difference over iPhone 3G.
The color of the dot in the position icon indicates the accuracy of the plotted position: Gray = none, Yellow = weak, Green = strong. Furthermore iNavX displays the accuracy in the Instruments view via the HPE: reading. I find iPhone 3G/3Gs to typically be in the 30' - 50' range where iPad 3G is often under 15'.
I considered not enabling the course up for devices without compass, but decided not to because COG does become decent once iPhone 3G has some velocity.
On devices with a compass, one can have iNavX use COG instead by turning "HDG:" in the Instruments view "Setup" to OFF.
