Apple is planning to launch multiple iPhones in June or July this year, supply chain sources tell RBC Capital Markets analyst Amit Daryanani. The sources don't have any information beyond that, but Daryanani says he expects Apple to launch an iPhone 5S and a low-cost iPhone. "The low-end iPhone will have the same 4-inch form factor as the iPhone 5, but will have a plastic casing and no Retina display," he predicts. "With a lower price point, AAPL will be able to target a growing and important part of the smartphone market (sub-$400 price band)."
