Right after its launch, we noted the sundry problems reported by new iPhone 3GS owners, but this is the first time we've heard tell of this specific one... and it seems like a doozy. It's unclear exactly what caused this, but what is apparent is an unattractive, brownish / pinkish discoloration on the above handset. The user claims it was caused by overheating during a period of using the GPS and 3G of the phone. Either way, it looks pretty crummy now, doesn't it? What about the rest of you with new, white iPhones? Anything to report? One more shot of this looker after the break.
