iPhone 3G's Case Not All Its Cracked Up to Be?

Who cares about the iPhone 3G's network performance!? Dang, iPhone 3Gs are showing up with cracks!

Apparently, according to the posts on Apple's support forums, several users have seen cracks show up on their cases. The cracks are hairline cracks, and don't appear to affect anything, but of course, when you're spending this kind of money ...

There are multiple threads on the support forums about this, and although there are reports of cracks in black iPhone 3Gs as well, the problem appears to either be more prevalent in white phones or - more likely - more visible on white phones.

As we know, the 3G model is all about cost reduction, so really, should users be all that surprised by these birthing pains?

Some have been successful exchanging their phones, but others have not been so lucky. They were told that since functionality of the phone was not affected, and since its wasn't a "known" issue, they couldn't get an exchange.

Others were told that cracks are not covered in the warranty. Of course, store employees were probably figuring that the people dropped the phones, but several posters swear they did not.

Readers, have any of you seen this issue? Did you get it resolved? Apple is usually pretty good at responding to these sorts of things, so we'll see what happens.
