According to reports the new iPhone 4 has "a gyroscope for six-axis

Apart from the fact that I only guessed (probably wrongly) that you
only needed 3 axes, I suppose this removes some of the problems in
using it as an artificial horizon?

They probably mean 3 axes of gryos and 3 axes of accelerometers. So
why did they leave out the 3 axis magnetometer?
With 3 accelerometer and 3 gyro axes they have enough to build an
attitude indicator that will work in a flight vehicle. There are
already lots of these around. Most of the sport aviation instruments
use some other inputs as well to achieve satisfactory performance,
GPS or air data being typical.
