We've seen smartphone adoption continue to grow seemingly with each new market share report that comes out, and now it seems that smartphone use has hit a bit of a milestone here in the U.S. According to the latest mobile report from comScore, which covers the three-month period ending January 2012, there are over 100 million U.S. smartphone subscribers (101.3 million at the end of January, to be exact). That's a jump of 13 percent from October 2011. The report also mentions that, at the end of January, there were 234 million people age 13 or older using a mobile phone in the U.S.
So which OSes are all of these smartphones running? Well, comScore pegs Android as the most popular platform with a share of 48.6 percent of all smartphone users at the end of January. Apple's iOS came in second at the end of the three-month period, finishing with 29.5 percent share. It's also worth noting that Android and iOS are the only two platforms in comScore's report that saw any growth during the October-January timeframe. In third place is RIM with 15.2 percent, a 2 percent drop from October. Rounding out the top 5 is Microsoft and Symbian with shares of 4.4 percent and 1.5 percent, respectively.
Finally, comScore gave us the skinny on the top mobile OEMs for the three-month period ending January 2012. Samsung was the king of the manufacturer hill with a 25.4 percent share of the U.S. mobile subscriber base. Behind Samsung was LG with 19.7 percent, and then Motorola in third with 13.2 percent. Finishing fourth was Apple at 12.8 percent, and RIM was on the bottom of comScore's top 5 with a 6.6 percent share.
As I mentioned earlier, it seems that smartphone adoption grows every time that we get a new report on it, so it's not a shock to hear that there are over 100 million smartphone subscribers in the States. Expect that figure to continue to grow as smartphones continue to become more affordable and more feature phone users decide to make the jump to a smartphone.
