iPhones are built by Foxconn, who also build devices for Samsung, Sony, LG, etc. There are tens of millions od iPhones and iPods out there, it’s inevitable that occasionally one has a problem. You have an equal chance of buying a competitors device that plays up just as much, and good luck with finding anyone to take responsibility for it. FWIW, I have an iPod 5G Video, a 3G Nano, a 3G iPhone, and an iPhone 4, and I occasionally get problems with the left earpiece cutting out on the iPhone 4. It’s an issue with the Shure SE215’s, not the phone, and I’ve had similar problems with the leads on Ultimate Ears phones too. Apple’s build quality is on a par with any Far Eastern electronic product, they’re all built in the same place, you just never hear about problems with some generic Samsung or Motorola or LG, device, the meeja’s only interested in highlighting problems with someone like Apple, and much of that is to do with manipulating Apple’s stock price for the hedge fund parasites, something I read on several RSS feeds yesterday.
