White iPhone 3Gs prone to hairline cracks?

Are white iPhone 3Gs prone to hairline cracks?

According to reports on MacRumors and the Apple Discussions forum, some users are discovering small hairline cracks forming on the white plastic shell.

At present it's hard to tell if these cracks are serious or merely cosmetic. However, since Apple is a company that relies of the cosmetic aspect of a device to differentiate it from the competition, maybe it doesn't matter.

I've not been able to find any reports of these cracks appearing on black iPhone 3Gs.

Anyone here hown a white iPhone 3G? See any cracks on yours? Oh, and no jokes about it being a cracking good phone, or how it is trying to compete with the CrackBerry ...
