So I just considered making a thread on this, since it hasn't been brought up before. Sure, the first gen iPhone is almost 3 years old, and it doesn't really make much difference any more, but I'm curious, as always. Take a look at the black plastic volume rocker. Press the up or down end, and look towards the middle. Is there a little scratch-looking line? It's split / cracked in the middle if you get to looking. No one I know has a first gen iPhone that doesn't have a crack in the center of the rocker. Then again, I'm a curious and OCD-like when it comes to my iPhone.
