Apple's total iPhone user base may reach as high as 100 million users by the end of 2011, according to Morgan Stanley analyst Katy Huberty. In a widely reported research note, Huberty expects to see about 42 million iPhones sold by the end of 2010 and that number could reach as high as 48 million, as reported in Fortune. Huberty's prediction is bolstered, at least in part, by Apple's recent announcement that it sold 600,000 iPhone 4 devices during the first 24 hours the new smartphone was available for pre-order.
