Apple’s iPhone 4S helps iOS stay ahead in the enterprise

Apple’s iPhone 4S (s aapl) has helped it regain ground lost to Android in consumer smartphone market share, but it’s also having a very positive effect on enterprise adoption, according to a new report. The iPad also remains virtually the only choice when it comes to tablets in business.

Enterprise mobile security provider Good Technology on Wednesday released its quarterly data report for the fourth quarter of 2011. The report detailed the progress of iOS and Android (s goog) devices in enterprise activations among its customers, which include half the companies on the Fortune 100, among others. Apple’s iPhone 4S was the big winner of the quarter, nabbing the top spot as the most-activated device, followed by the iPhone 4 and iPad 2 at Nos. 2 and 3, respectively.

The 4S represented 31 percent of all device activations counted during the quarter, nearly matching the total for all Android handsets, which accounted for 35 percent of all smartphone activations. Apple’s iPad 2 and iPad together accounted for 94 percent of all tablet activations.

Much like we’ve seen with new consumer device purchases, the release of Apple’s iPhone 4S in October began the reversal of a trend in which new Android activations were approaching Apple’s numbers, as you can see in the chart below. From October to December, Good saw a steady monthly increase in the percentage of iOS activations, matched by a decrease in Android device activations. Good says bring-your-own-device (BYOD) policies likely had a strong impact on Apple’s enterprise success with the iPhone 4S.

A new phone from Apple was bound to incite a buying spree, but the numbers have remained strong in the months following launch. It will be interesting to see if the trend of growth continues, both in the consumer and enterprise markets, now that the 4S has been on the market for some time.
