iPhone 4S vs iPhone 4 - Speed Test

A quick video to show the difference in speed between the iPhone 4S and iPhone 4.

Just to clarify a few points.
I do not claim this to be in any way a scientific test. I did try to hit the screens at the same time, most are pretty accurate.

The iPhone shown is a 3 month old Apple referb. Both phones had just been installed with iOS5 (reformat) and rebooted.

The clips are edited to remove the footage of me closing the apps. Each app launch was made with no other apps running.

Both phones are connected to the same wireless network.
