Piper Jaffray analyst Gene Munster, said: "We believe that if the 21st is the actual ship date, Apple could sell 6-10 million iPhone 5 handsets in the final week of September barring supply issues."
According to figures, each iteration of the iPhone sells more than the other; the iPhone 4S sold more than 4m units three days after going on sale; its predecessor, the iPhone 4, sold 1.7m, while the iPhone 3GS shifted over 1m.
Based on these figures, Muster was able to conjure up a rough estimate of how many units of the next-gen iPhone Apple is likely to shift in its first week (10m units) and during the September quarter (a whopping 26-28m units), which punches above the current Wall Street expectation of 23m units during the same period.
If the targets are met, it would make the iPhone 5 Apple’s most successful smartphone ever.
