Since the white version of the Apple iPhone hit stores last week, the internet has been replete with stories that it is slightly thicker than its black predecessor. Since our test-happy cousins at Consumer Reports have equipment to measure the thicknesses, they decided to do so.

From Consumer Reports:

But when we compared a white iPhone 4 with a black iPhone 4 in our Yonkers, NY, lab using high-quality calipers, we found they were both the same thickness (0.37 inches). this supports Apple’s assertion that the devices are the same size.

What’s more, we also tried several cases we bought for the black iPhone during its antenna trials. These were the Griffin Etch Graphite, a hard-backed case with soft rubber-like sides; Incases Snap Case, a hard plastic case with a hard plastic sides; and the official iPhone 4 Bumper. All fit the white iPhone 4 as well as they did the black version.

CR is still testing the white iPhone to see how it stacks up with the existing versions of the device.
