According to a ChangeWave Research survey, Research in Motion’s BlackBerry accounts for almost 3 of 4 smartphone purchases in the enterprise with 73% of the market. The survey also has the BlackBerry poised to pick up another 4 to 5 points.

Although the BlackBerry is, pretty much, crushing everyone, Apple’s iPhone is coming on strong. The iPhone currently has 5% of the enterprise market but ChangeWave predicts that it will pick up at least an additional 6% and could jump all the way to second place behind RIM if second place Palm at 18% and third place Motorola at 9% continue to free fall.
