Did the iPhone 4S need a new design ?

iPhone 4S



Everyone loves a new design. Its what tells it apart from the old one. And everyone likes to see Apple's gadget with the new design. But how could Apple have changed the design ? 


Make it curved rather than boxy, perhaps ? But why do that when all iPhone models prior to the iPhone 4 were in fact curved and yet the iPhone 4 sold more than all of them combined.


Maybe increase the screen area ? But then the border of the Phone on the side of the screen would have to be removed and wouldn't that destroy the classic look of the Phone ?


Of course, I won't argue with the fact that we expect Apple to come up with something new like that but if they're fine with their design of the phone ( which just won the "World's thinnest smartphone" rights ) then so am I. After all, its less than a centimeter thick.
