Symbian 9.5 comming up
Symbian, the mobile OS company is expected to announce an upgrade to its OS to version 9.5 at CTIA, that hopefully will decrease its reliance on smartphones, its main patron Nokia, and also ward off competition from fast growing rival mobile operating systems, Windows Mobile and Linux.
With the new OS upgrade, Symbian is trying to increase its appeal, betting that it can sneak its way into more mainstream handsets (called feature handsets in industry parlance.) The new OS is going to make more efficient use of memory, battery and other resources, making it more flexible for use in mainstream phones.
The new OS will allow Wi-Fi 3G roaming. Push-email and VoIP run over WiFi when in the office and automatically switch to 3G when on the move. In addition, Symbian has added real-time networking ensures that VoIP is not interrupted when other IP-based services, such as web browsing or push email, make a connection.
