Apple on Monday said it had received record pre-orders for its new iPhone models, and that some customers will have to wait for the larger-screen versions of the smartphones. Demand for the new iPhones exceeds the initial pre-order supply and while a significant amount will be delivered to customers beginning on Friday and throughout September, many iPhone pre-orders are scheduled to be delivered in October, Apple said in a statement. Apple last week unveiled the iPhone 6 and iPhone 6 Plus, in a move aimed at satisfying consumer preference for bigger smartphone displays. The announcement means Apple may see shortages and long lines at its retail stores when sales begin on Friday.
