Analyst estimates are ranging widely on how many iPhones Apple sold during the last quarter, Fortune writes. Tavis McCourt of Morgan Keegan represents the conservative end of the spectrum, calling for only 10 million units. Rodman & Renshaw's Ashok Kumar, by contrast, is the most optimistic, suggesting that as many as 13.3 million phones may have been shipped. A consensus figure puts the number at 11.8 million.
