When the iPhone 4 was announced, there was one feature many of us were skeptical about: the gyroscope. I think the problem was that many didn’t catch the differences between an accelerometer and a gyroscope, and Steve’s jenga demo surely didn’t help in making these differences very clear. Ngmoco’s first FPS for the iPhone 4 was the first app to truly take a adavntage of the new technology.
Acrossair, developers of many AR apps for iPhone, decided to give us a demonstration of how much their AR browser can be different whether it’s run on an iPhone 4 and a 3GS.
