Analyst firm IDC has upped its forecast for smartphone shipments this year. It now thinks that 269.6 million ‘converged mobile devices’ will ship in 2010, based on sales of 119.4 million units in the first half of the year alone. If the full-year prediction is correct, it would be a rise of 55.4% on 2009’s 173.5 million smartphones. IDC has also put numbers on the market share of the various operating systems. In 2010, it sees Symbian leading with 40.1%, followed by BlackBerry (17.9%), Android (16.3%), iPhone (14.7%) and Windows Mobile (6.8%). By 2014, it thinks Symbian will still be tops with 32.9%, but that Android will have overtaken BlackBerry (24.6% and 17.3% respectively), with Windows Mobile hot on the heels of iPhone (9.8% and 10.9% respectively).
