I want to see this feature implemented in the iPhone/iPod Touch.
Basically, when you're on the springboard. Give your iPhone a shake to the right or left and the springboard page goes to a different page. Example: I shake my iPod Touch to the right, the springboard page goes to the 2nd page. If I shake left, it goes to the first page and so on.
If you don't understand please ask me with detail.
