Good Technology has analyzed the mobile devices activated by their thousands of enterprise and government customers over the fourth quarter of 2011.

Whereas the iPad and iPad 2 were the story for most of 2011, in Q411, iPhone 4S and iPhone 4 took center stage and strongly dominated activations in the enterprise. The mid-October release of iPhone 4S cause iOS activations to skyrocket month over month. iPad and iPad 2 remained dominant with 94% of activations in Q4, while Android tablets account for 6% of tablet activations.

Good Technology notes that holiday season sales are not reflected in this report as new “Bring your Own Device” (BYOD) purchases in mid-to-late December were most likely activated when workers returned to the office in the new year. Good expects a surge of activations in Q112 as employees bring the phones they received over the holidays into work for the first time.
