The iPhone is second in planned corporate smartphone buying, and first in corporate smartphone satisfaction, according to the latest research from ChangeWave. A February 11-15 corporate survey of people involved with IT spending decisions showed that despite its 5% share of the corporate market, the iPhone ranked first in corporate smartphone satisfaction, with 59% of Apple’s business customers saying their company was very satisfied with the iPhone. Blackberry maker Research In Motion came in second with 49%, a drop of 8% from the previous survey. RIM was the dominant leader in planned corporate smartphone purchases, however, with 77% of companies planning to purchase a smartphone in the next quarter saying it would come from RIM. Apple’s iPhone came in second in this category, with 11%, down 3% from its previous high. In its invitation to next week’s iPhone software roadmap event, Apple said it would show some “exciting new enterprise features” for the handset, which may boost its attraction in the corporate market.
