Mystery of half million missing iPhones

Do you have one of the 512,000 lost iPhones?

Instead of studying the company and telling us about the future of Apple's stock and expected performance, analysts at Piper Jaffray are trying to track down around 500,000 iPhones that seem to have gone missing.

The company sold 3.7 million iPhones to US customers in the three months ending on 31 December, according to Apple during a recent conference call with its investors. However, the device's carrier in the US - AT&T - claimed only 2 million of those iPhones were activated in the same time period.
