Good news. iNavX 3.0.2 has course up. It has been submitted to Apple so I expect it to be available within a weeks time.

I thought there was a discussion where course up wasn't important?

Course up was a feature that some users desired. Many users were ambivalent and some users did not want it. It is now there, use it if you want.
Using computers for marine navigation is still relatively new. As more and more people adopt it, workflow methods and SW will evolve.

The future of marine computing will be augmented reality. we've already seen a preview of it on that Americas cup boat that was victorious this year.
Imagine sunglasses with a heads-up display, buoys highlighted, night vision, 3d rendering of the seabed superimposed, visual representation of the wind, tides, currents, AIS traffic headers, zooming...
early days, but it will happen...
Check out
Pairsite's Theodolite for an example of what can be done with just an iPhone 3GS.

iNavX 3.0.2 is now available as a free update. Changes include -
Course Up chart orientation. If green border, tap orientation indicator in lower left hand corner of chart for course up orientation.
New graphics for Instruments including Analog SOG and BSP.
New graphics for Instruments including Analog COG and HDG.
More efficient route creating/editing in "Route" view.

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'.

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.
