Apple is apparently testing some new gestures for the iPhone. As you can see in this video, one developer decided to ignore Apple's developer agreement and show off the gestures on camera.

The main gesture he is showing is a 4 finger swipe to switch between open apps. I have to say, this looks awkward. Apple will likely tweak these before they are ever released which is why we probably haven't seen these before, but it's still fun to see. This gesture also looks like it was made more for the iPad than the iPhone. We'll have to just wait and see.
