"Four in ten (39%) adults now own a smartphone, a 12 percentage point increase on 2010. Forty-two per cent of these now say that their smartphone is the most important device for accessing the internet, with over four in ten (42%) regularly using social networking sites and half (51%) using e-mail.

Overall, the time spent using the internet on mobile devices is up by a quarter (24.7%) year on year, with the overall volume of mobile data consumed doubling in the 18 months to January 2012.
