Early iPhone adopters are starting to crack.

Reports from technology Web sites like Engadget are coming in that iPhone 3G buyers are starting to notice small cracks in their new wonder cell phones.

The backs of the new iteration of the popular Apple phone/iPods are now constructed of plastic instead of the metal to allow better antenna reception for the 3G Internet connectivity and GPS.

But frustrated buyers have noticed hairline fractures appearing around the curved edges of the device, especially the white iPhones where dirt can't hide as easily.

Apple has not commented yet about the possibly faulty construction, but some sites have reported that angry owners have been successful at exchanging their phones at local Apple stores.
