Speaking of making big improvements to the iPhone via some VERY simple changes: wouldn’t it be cool if you could scroll past the last page of your iPhone apps, and have it wrap around to the beginning? Currently, going from page 1 to page 7 takes six swipes to the left, and from page 7 to page 1 take six swipes to the right. If you could “wrap around” you’d be able to do either in ONE swipe.
Probably too late to get a patent on the “wrap around” idea but when you see it on your iPhone just remember you heard it here first.
