Apple (NSDQ: AAPL) has finally owned up. After weeks of speculation about what the lack of iPhones in US stores actually meant, Apple Chief Financial Officer Peter Oppenheimer blamed it on people wanting to buy unlocked iPhones and on the company’s own underestimate for demand after January, reports Dow Jones via Cellular News. Apple had expected a “sharper seasonal decline” in iPhone sales—but were caught short, thanks to the surging overseas grey market continuing to suck up any available stock. Oppenheimer did not give a precise figure on the number of iPhones that have been unlocked, but called them “significant.” Oppenheimer said Apple was on course to sell 10 million iPhones this year. Various estimates put the number of iPhones already sold at 5 million.
