69.5 million people in the US owned smartphones at the end of February, according to the latest data from comScore. Its stats show Android overhauling BlackBerry to become the most popular smartphone OS in the US in terms of install base, with 33% of smartphone owners having an Android handset, versus 28.9% for BlackBerry and 25.2% for iPhone. Note: these figures are smartphone only, so do not include iPad or Android tablets, nor do they include the iPod touch. comScore also says that 17.5% of overall US mobile subscribers (everyone, not just smartphone owners) listened to music on their phones in February, up from 15% in November 2010. However, 36.6% used downloaded apps, and 24.6% played games.
