26m iPhones in a three month period. Apple’s Q3 2012 results are out, and while the huge year-on-year growth for iPad is an eye-catcher, it’s the shifting sales of the company’s flagship smartphone that have split opinion. For many – Nokia, for instance, or HTC – 26m sales would be the very definition of “a good problem to have”, but for Apple it’s not so straightforward. While the company has seen 28-percent year-on-year growth for the iPhone, its also seen a 26-percent drop quarter-on-quarter. So, is the iPhone stumbling, or is this all entirely understandable?
