Apple’s much-awaited iPhone 5could hit the 10 million sales mark in its first week, an analyst has predicted. Apple is expected to launch the iPhone 5 at an event on September 12. Some reports suggest that the new phone will reportedly go on sale on Friday, September 21. With that date in mind, Piper Jaffray analyst Gene Munster projects iPhone 5 sales of anywhere from 6 million to 10 million, CNET reports. According to the report, last year, Apple sold 4 million iPhone 4S units during that phone’s first three-day weekend in October. The analyst predicts that a full 10 million in sales over a little more than one week seems attainable this year, as long as there’s enough supply to meet demand. Overall, the analyst is eyeing total iPhone sales of at least 26 million units for the full September quarter, higher than the average Wall Street estimate of 22 million to 23 million, the report said.
