U.S. now home to 100 million smartphone users, says new report

According to comScore's latest report on the U.S. mobile phone industry, there are now more than 100 million smartphones in use in the country. This is a 13 percent jump from where the number stood back in October, 2011, and demonstrates the continued demand for smartphones from the American public.

To be more precise, comScore says that there were 101.3 million smartphones in use in January. Unsurprisingly, Android and iOS were the most popular platforms, with Android claiming 48.6 percent of the market (a 2.3 point increase from October) and iOS owning 29.5 percent (a 1.4 point increase). RIM's BlackBerry OS continues to lose share in the U.S., falling 2 points to 15.2 percent share, while Microsoft's various mobile Windows platforms claimed 4.4 percent (down 1.0 points) market share and Nokia's Symbian took a 1.5 percent (down 0.1 points) share.

The top five mobile phone makers in the U.S. remained in the same slots for January, though fourth-place Apple was the only one to gain any market share (up 2.0 points). comScore says that 234 million Americans aged 13 and older used mobile phones in the three month period ending in January.
