After 10 months of delays, the white iPhone 4 has arrived, and at closer inspection it turns out it's not only late, but also thicker than its black sibling. The difference is very small, 0.2 millimeters to be more precise, but it's enough to give headaches to some users who would find their cases wouldn't fit on the white iPhone 4.

Ryan Cash, who posted comparison shots of the two models on his blog, first noticed the difference in thickness between the white and black iPhone 4. He didn't measure the devices, but the difference is noticeable with the naked eye. Then, the TiPb blog took the measurements and elucidated the mystery: indeed, the white iPhone 4 is 0.2 millimeters thicker than the black one.

The difference, from roughly 9.3mm thickness of the black iPhone to 9.5mm of the white model, doesn't come from the steel frame of the device, but from the white glass part on the front of the device. Apple doesn't list any difference in thickness on its website between the white and black iPhone 4.
