This is probably the first (if not, it's definitely among the few clips) video in which I have 2 iPhone 4 terminals (white/black) placed next to each other for a small comparison. From the point of view of design, the 2 terminals are identical, except of course the color of the casings. From a hardware point of view, we cannot verify, but they should be identical because we are talking about the same generation of iPhone and Apple does not change the hardware configuration between the white/black models. You can see that the only differences are on the back case, where the strips on the white terminal have different colors than those on the black terminal. However, that white terminal looks somewhat strangely colored, the button having a different color than the rest of the case.
The owner claims that the white terminal was taken from AT&T USA, but it is difficult to prove that it was really taken from there, anyway it seems quite real and we all know that Apple factories "lose" terminals from time to time.
