Smartphones now account for nearly 50 percent of U.S. mobile subscriptions, according to a new report.

While it's really not surprising smartphones are increasingly on the rise in the U.S. (I mean, isn't everyone checking their Facebook/Twitter on their smartphone all the time?), it is impressive at how quickly the devices are being adopted.

In February, 49.7 percent of mobile users owned a smartphone, a 38 percent increase over February 2011, when 36 percent of mobile users owned smartphones, according to the research firm Nielsen.

Android is the most popular smartphone among mobile subscribers, with 48 percent of owners saying they owned the device, according to Nielsen. Apple came in second with 32.1 percent of the market share. Blackberrys were third with 11.6 percent.
