You have to make sure you hold you phone on its side while loading the 
augmented reality example. I have a milestone with 2.1 on it and it works, but 
just barely lol.

Neither of the Augmented reality demos work at all for me on a Galaxy S2 
regardless of the orientation.

HTC Desire HD and it doesn't work regardless of orientation when the example 
starts.
