How many smartphones are in use?
With iPhone, Android and Blackberry devices all the rage, sales of smartphones are on the rise globally – but they still have a long way to go before they surpass sales of regular mobile phones. Smartphone sales reached 472 million in 2011, up 58% from 2012, according to Gartner. But smartphones continue to lag overall mobile phone sales, which Gartner says hit 1.8 billion. As of November 2011, smartphones accounted for just 27% of all mobile phones in use worldwide, according to a study by Vision Mobile.
