There are a lot of words and phrases that could be used to describe Apple’s fiscal first quarter financial results. Amongst them: incredible, unbelievable, record-breaking and earth-shattering.

Strong (to put it modestly) sales of iPhones, iPads and Macs produced over $46bn in revenue and a mind-boggling net profit of more than $13bn.

When it came to the iPhone, the company’s latest, the iPhone 4S, proved to be a winner, with more than 37m units sold in the quarter, which covered the all-important holiday shopping season.

But it wasn’t just consumers snapping up shiny new iPhones. According to a report (PDF) by enterprise mobility company Good Technology, the iPhone 4S proved to be a hit in the enterprise as well.

The firm, whose customers include half of the Fortune 100, saw iPhone 4S activations account for 31% of all new phone activations across its customer base in the calendar fourth quarter of 2011. This is a significant number, as it represents “the highest Good has seen for a single iOS or Android device model since introducing support for those platforms in December 2009.”

The second-most popular smart phone device in the quarter was the iPhone 4, which accounted for just under 18% of all activations. And, not surprisingly, in the tablet category, another Apple product, the iPad, also dominated, with approximately 94% of all tablet activations being iOS devices.

All told, iOS-based products accounted for more than 70% of all smart phone and tablet activations in Q4, suggesting that one of the biggest questions facing Apple (can it succeed in the enterprise?) has been answered quite clearly. That seems to be in due in large party to BYOD (bring your own device) programs, which let employees select their own devices.

The question now is whether Google’s Android can play catch-up in the enterprise. According to Good Technology SVP John Herrema, it’s all about the smart phone for Android — at least for now. “Android continues to be driven by smartphone activations and we expect to see continued Android growth in 2012 as Good’s customers continue to ramp up their BYOD [bring your own device] programs,” he stated.
