iPhone 4 white is thicker than the black edition

This is some hot news I think. It's true that white iPhone 4 which released over 28 countries on yesterday is 2mms thicker than the black edition. It's the same price and same hardware. Then how it can be 2mm thicker than it's successor the black iPhone 4... Some possible answers have been found from 9to5mac.com and they are the first to announce that white edition is thicker than the black edition... Here's the exact review...
1. Apple has introduced a fix for the iPhone 4’s antennae woes. The iPhone 4 has a hardware
flaw that causes the phone to lose reception
when held a certain way. At face value, it
doesn’t look like the phone carries any kind of design differences.
2. The white paint for the new iPhone 4
required a different game plan. The white
iPhone’s case did not insulate the its camera’s flash and leaked light when taking photos,
according to reports. White iPhone 4 parts also
caused some issues with the phone’s proximity sensor, which disables the screen when talking
on the phone so owners don’t accidentally hang up, according to Apple’s Steve Wozniak.
3. The white iPhone needed additional
protection from external light sources. Any light
leaking into the phone could disrupt the iPhone
4’s screen and make the image less clear, which would be a sore point for Apple because
it touts its “retina display” as one of the best smartphone displays in the business.
4. Apple is just trolling tech geeks everywhere
to try to generate some additional publicity for
the white iPhone 4 — because even a 0.2 millimeter difference is enough to generate
news buzz when it comes to an Apple product.
