By the end of March 2005, shipments of Symbian OS phones exceeded an average of two million per month, and cumulative shipments since Symbian’s formation reached 32 million phones. Also at that time, there were more than 4500 commercially available, third-party applications for Symbian OS phones. Year on year, phone shipments have been virtually doubling – and that trend appears likely to continue, or even increase, for the foreseeable future.
