Apple's long-awaited white iPhone 4, which hit stores April 28, is expected to be another smash for Steve Jobs. But how much will it benefit the American economy? Though invented in the U.S., the iPhone is manufactured in China, so, ironically, iPhones sold in the U.S. add to the trade deficit with the Middle Kingdom. Yet China contributes almost nothing to the value of an iPhone; it does little more than assemble parts from elsewhere. A host of other countries, including the U.S., benefit more from producing the world's hottest gadget.
