Jobs showed the 3GS next to the iPhone 4 and was demoing the improved screen on the iPhone 4. He was showing the video output via a cable from both devices, and not a camera above each phone.
How is this demoing the screen and not the video output? Would you need a camera above both to show differences in the screen?
