Apple sold 3.89 million Macs during the quarter, representing a 27 percent unit increase over the year-ago quarter. The company also sold 14.1 million iPhones in the quarter, representing 91 percent unit growth over the year-ago quarter.

Apple CEO Steve Jobs noted in a statement that iPhone sales handily beat “the 12.1 million phones RIM sold in their most recent quarter.” Jobs also said that Apple still has “a few surprises left for the remainder of this calendar year,” no doubt referring to the special event on Wednesday.

During the quarter, Apple sold 9.05 million iPods, representing an 11 percent unit decline from the year-ago quarter and they also sold 4.19 million iPads during the quarter. The iPad wasn’t available a year ago, so no comparison can be made.

Apple CFO Peter Oppenheimer said looking forward to the first fiscal quarter, Apple expects revenue of $23 billion.
