Apple appears poised to continue its string of setting new year-over-year records for quarterly iPhone sales, based on new data from Morgan Stanley analyst Katy Huberty. According to Huberty's "AlphaWise" smartphone tracker, Apple is on track to ship 42 million iPhones during the January-March quarter, topping the March quarter record of 37.4 million iPhones set last year. Morgan Stanley's AlphaWise tracker follows Google Trends data, and the firm touts that it has been more accurate than analyst consensus in recent quarters. Analyst consensus and Morgan Stanley's own supply chain estimates have been pegging Apple's iPhone shipments for the quarter at 38 million units, but demand numbers appear likely to push that number up.
