Another difference of White iPhone 4, is it a bit thicker?

Another difference of White iPhone 4, it’s thicker than black iPhone 4?
Really?

Look at the images posted on 9to5mac below:

The white iPhone 4 really looks a bit thicker, but they take both images of white iPhone 4 and black iPhone 4 from different angle. Hence, the white iPhone 4 seems a bit thicker.

But look at the close-up picture of white iPhone 4 and black iPhone 4 below:

Do they really seem to be have different thickness?
While apple didn’t post any different specification between black and white iPhone 4. The white iPhone 4 have the same specification of the black iPhone 4.

I don’t it really matter, only a few difference thickness, 0.2mm, I bet you even didn’t notice it!

What do you think guys?
