Every quarter, Nielsen releases a report about the current status of the Mobile industry as far as operating systems and sales are concerned. A study about recent smartphone purchases during Q4 of last year, showed that consumers, 44.5% of them, have bought iOS-powered phones in December alone, almost 20% more than October. 57% of those purchases were for iPhone 4S.
While those numbers may be impressive, there were still not enough for iOS to dethrone Android OS, whose percentage fell from 51% in October to 46.3% in December. Expect these numbers to go up in the first quarter of 2012 as the the sales of the iPhone 4S slow down and as more high-end Android devices release.
