Respected analyst Ming-Chi Kuo with KGI Securities recently published a research note (via MacRumors) in which he claims that Apple (NASDAQ: AAPL) will ship around 100 million units of its upcoming mainstream iPhone with a 6.1-inch liquid crystal display (LCD). Such shipment figures would make it the most popular of Apple's upcoming iPhone models, as Apple usually sells around 200 million iPhones each year. Although Kuo has published many of the key specifications of the device, he doesn't appear to be entirely sure as to how Apple will price it.
