Nerval's Lobster writes: Apple managed to sell nine million iPhones over the weekend, with the company claiming its initial supply of high-end iPhone 5S units completely sold out. Apple didn’t sell out of the new iPhone 5C, its plastic-cased (and cheaper) alternative to the iPhone 5S; models are still available for shipment within 24 hours from Apple’s online store. And the iPhone 5S selling out is no surprise: in the weeks ahead of the new iPhones’ launch, rumors persisted that the initial production run of the device was relatively small in scope, which would make it far easier for Apple to sell out of its first batch. But how many iPhone 5C units did Apple actually manage to sell? In August, KGI Securities analyst Ming-Chi Kuo suggested that Apple would produce just over 5 million iPhone 5S units ahead of the device’s launch weekend; if that number’s accurate, and Apple sold every single one, it would mean Apple sold roughly 4 million iPhone 5C units in order to reach that 9-million-sold figure for both models. That’s an impressive figure for any smartphone, of course, and it could quiet some of the naysayers who have spent the past several months suggesting that Apple’s best years are behind it.
