After the widely acceptance of Symbian Anna version of their Symbian^3 Operating System, Nokia comes up with their new version called Symbian Belle on their high end smartphones such as Nokia N8,C7,701 etc. Inspired from the competing OSes such as Google Android OS and Apple iPhone OS, Nokia introduced many new features in Belle. The notable features of Symbian Belle are the large sized icons (similar to iPhone), the notification panel (similar to Android) and NFC (Near-Field Communications) for better and easy communication.
Symbian Anna is an update to Symbian^3, released by Nokia in April 2011 as part of the launch of the X7 and E6 smartphones. Symbian Anna includes such improvements as a new browser, a virtual keyboard in portrait orientation, new icons and real-time homescreen scrolling.
Symbian Belle is an update to Symbian Anna. On August 24, 2011, Nokia announced Belle officially for 3 new smartphones, the Nokia 600, Nokia 700, and Nokia 701. They also announced that Belle would be coming to all existing Symbian^3 devices soon. Symbian Belle adds to the Anna improvements with a pull-down status/notification bar similar to Android, deeper NFC integration, free-form re-sizable homescreen widgets, and six homescreens instead of the previous three.

In the summer of 2011 videos showing an early leaked version of Belle running on a Nokia N8 were published on YouTube.
This new version brings more improvements to the homescreen than Anna did. The homescreen now consists of up to six rather than three panes and the widgets that live on those panes will be available in five different sizes. User can add & remove homescreens. The widgets can be re-sized too, which gives the user even more flexibility.
Symbian adds an informative lock screen which tells about missed calls, messages in the inbox and more, so that one can check the phone at a glance. Adding colored wallpaper to the lock screen is also possible now.
Belle includes new apps from Microsoft – Lync (IM for businesses, like Microsoft Communicator), Sharepoint, OneNote, Exchange ActiveSync and PowerPoint Broadcaster. Belle continues Nokia’s push towards an NFC-enabled world. Pairing is now simple. Just tap two NFC-enabled phones together and that’s it. To unpair them, just tap them again.
On February 11, 2011, Nokia announced that it would migrate away from Symbian to Windows Phone 7. The future of Symbian OS is in dark. However, it is very promising to see newer versions of Symbian OS coming out for new smartphones.
