Question

Can the iPhone determine if you\'re facing north, south, east or west?

Answer 1

To my knowledge there is no compass in the iPhone 3G. Unfortunately, unless I'm missing something I don't think looking at GPS and accelerometer data will help you determine which direction the iPhone is facing - only the direction you're travelling. Sorry.

UPDATE: Note that the question and this post was written when iPhone 3G was the current model, since then Apple has released the iPhone 3GS which introduced a compass.
