As promised, Nokia took the wraps off its latest update to the Symbian operating system today.

Dubbed Symbian Belle, the OS brings a number of interface improvements, new apps, and enhanced feature support. On the UI front, you now get six instead of three customizable home screens, and widgets can now be resized to your liking. In addition, the company has added Toggle widgets, so you can more easily complete tasks, such as turning on/off wireless connections and changing profiles.

In Belle, the status bar now incorporates a pull-down notifications tray, and the lock screen provides more information, such as missed calls and new messages. Nokia also promises better multitasking with larger views of open apps, so you can more easily see what's going on at a glance and quickly switch among tasks.

On the features front, NFC support is extended so you can share pictures, connect to accessories, and check in with a simple tap of a button. Finally, the new OS brings more robust business apps from Microsoft, including Exchange ActiveSync, Sharepoint, OneNote, PowerPoint Broadcaster, and Lync.

Symbian Belle will be available to existing Symbian 3 devices, such as the Nokia N8, Nokia E7, Nokia C7, and Nokia 500, and on new handsets in the coming months. To see the new improvements in action, check out the YouTube video above.
