iPhone 4 Bottom Screw Confusion

[mgmusicman94]

Hey guys. I was just watching the WWDC keynote from the other day and I realized something strange about the bottom screws on the new iPhone 4. In the keynote, Steve Jobs put some pictures up of the new iPhone, similar to the ones on the Apple website. I realized that the pictures from the keynote had a phone with normal phillips head screws in the bottom. But on the apple website the phone has 5-point star screws in it. I wonder what Apple will build the new phones with. Maybe the pictures in the keynote were of a prototype? Photos attached below. (First is from the keynote, second is from apple.com)

There is already a thread about this somewhere around here. The iPhone 4 with a phillips head screw is a prototype. Apple went with a Torx head on the final design.
