first when i saw a leak of the iPhone 5, i hate the bottom (speaker section) of the new iPhone 5, it looked ugly with its speaker grill with so many dots. after the unveiling day, the iPhone 4S bottom now looks uglier lol, it looks ancient and i prefer the bottom of the iPhone 5. i love the aluminium design on the back, but what scares me is they combined it with a glass instead a plastic for the signal to go through. with iPhone 4S, when u drop the back of the iPhone, it's either crack or no scratch at all. when it's cracked, you can buy the backplate for cheap and easily can be changed. with the iPhone 5, when u drop it on the back, i'm sure there will be dent in the alumunium section and the worst thing is when u crack on of those small glass back, how do u change it? u've got to change the whole unibody case this iPhone 5 might looks sturdier, but i prefer the all glass back because u can exchange it for cheap and easy.
