Apple's 10-Million-Mac Year Also Its 10-Million-iPhone Year?

Apple’s fiscal fourth quarter will end Tuesday, Sept. 30. And when it does, it will have been a five-million iPhone quarter. This according to Piper Jaffray’s Gene Munster, who, in a research note to clients, said the iPhone will account for a “meaningful percentage” of Apple’s booked revenue for the first time ever this quarter.

If he’s right, Apple (AAPL) would seem on track to hit its goal of 10 million iPhones sold in calendar 2008. And with some analysts predicting that Apple will sell 10 million Macs this year, 2008 may well prove a landmark year for the company.
