For Apple’s quarter ended two weeks ago, the most important metric that analysts are looking at is how many iPhones have been sold between January 1st and March 31st. About 48 analysts have been polled and the number has been evenly divided between professional and independent sources. The independent sources tend to go on a limb than the pros. Wall Street analysts have been predicting between a range of 26 million to 33.1 million. The average by Wall Street analysts is 30.5 million, which makes year-over-year unit sales increase by about 63.8%. The independent analysts peg the number at about 37.2 million, which is a 99.9% increase from the same quarter last year. The average here is about 35 million iPhones being sold, which is an 88.5% increase year over year.
