What analysts think about Apple's iPhone sales

Apple is announcing its quarterly earnings on July 19 and analysts are prepping their sales estimates for the big day. Philip Elmer-Dewitt of Apple 2.0 compiled a handful of these projections which range from a high of 20.25 million from Nicolae Mihalache of Traderhood down to a low of 15 million from Charlie Wolf of Needham.

The average estimate falls at 16.9 million units which is a 101% year-over-year increase and a slight drop from the 18.6 million sold last quarter. In four years of iPhone sales, DeWitt estimates Apple has sold over 125 million handsets.
