Piper Jaffray analyst Gene Munster estimates that the iPhone 5 could sell 26 to 28 million devices in the September quarter.
Cupertino could sell 6 million to 10 million new iPhones in the last 10 days of the month, Munster says.
His estimates seem more positive than the current ones which point to 22 million to 23 million units in the quarter, given the slow iPhone sales.
“While our model, along with most of the Street, assumes an October launch, we believe that a September launch could result in the final 10 days of the month generating 6-10 million iPhone 5 unit sales, which would likely shift out of December. We believe if iPhone 5 launches in September, Apple could sell 26-28 million units in the quarter (this takes into account iPhone sales slowing dramatically from September 12-20, which is announcement to availability). This would imply 8% upside to the Street’s current $35 billion in revenue and 12% upside to EPS of $8.46.”
The iPhone 5 is expected to be unveiled at a September 12 event, followed by a release on the market nine days later.
