The iPhone 4S, introduced by Apple on October 4, seems to be the one to blame for the closing gap between Android and iOS in the last quarter of 2011, according to research company NPD.
If the market share (by sales) in the U.S. for iOS was 26% in the third quarter of 2011 (trailing behind Android’s 60%), the same number jumped to a whopping 43% by October and November (to the detriment of Android which dropped to 47%). Numbers probably would have indicated an even closer race and gap between the two if December (and Holiday season) numbers were included, where Apple is believed to have activated more iOS devices than Google.
However, according to NPD, the two platforms combined account for 90% of the U.S. market share, making it “a two-horse race”. Needless to say that Android will quickly pick up the pace with its new Ice Cream Sandwich platform and Nokia is probably going to boost Windows Phone sales in the U.S.
