Apple said the iPhone X won't begin pre-orders until Oct. 27. The device will start shipping on Nov. 3. Even at that time, however, availability of the iPhone X may be limited. Component shortages are likely to have a major impact on production of the iPhone X, according to well-known Apple analyst Ming-Chi Kuo of KGI Securities. The device "will remain in severe short supply for a while," Kuo wrote in a research note this week.
