Now, lots of iPhone fans have got their desired white iPhone 4 today. It was believed that the white version of iPhone 4 is the same as the black version expect the color.
Now some meticulous users have found that there is, in fact, a difference between the two versions.
From the posted pictures of the two versions side-by-side, the white version of the device is ever so slightly thicker than the black version. By measurement, the difference is roughly 0.2mm. It’s a small difference, but enough that the white iPhone 4 wouldn’t fit in his Incase slider case.
Also the headphone and dock ports in the white version are made by a gray plastic material.
