Nokia has unveiled the most recent version of the Symbian operating system, called Belle. This revamped Symbian OS offers users newer widgets, apps and customizable options along with built-in support for NFC.

Nokia also introduced the three Nokia handsets that will be among the first to use the Belle OS, the Nokia 600, 700 and 701. Belle update will be available for free for the Symbian Anna running devices and updates for N8, E7, C7, C6-01, X7, E6 and 500 Symbian Belle have been confirmed.

“Symbian Belle and the three new handsets we are launching today show our commitment to continue delivering Symbian products that allow people to choose what is most important to them in terms of user experience, design, functionality and price. These will not be last products or updates we will deliver on Symbian,” Ilari Nurmi, vice president at Nokia, said in a statement.

What’s new

There are a host of exciting features packed into the hot new range of smartphones. Nokia 600, 700 and 701 offer something for everyone.

Free-form, resizable, and live widgets: Widgets such as the clock, email, music player, and calendar have been redesigned. They come in five different sizes now. The update debuts toggle widgets for tasks such as toggling Bluetooth on\off and changing profiles.

More homescreens: The maximum number of homescreens has risen. Experience something new with 6 customizable homescreens.

Fresh new look: The navigation and options bar now sports a new look, similar to that seen on the N9.

Improved status bar: The status bar sports a pull-down notification tab that gives access to common settings and notification regarding incoming messages, missed calls, and more.

Brief hardware specs of the new handsets

The upcoming Belle-powered Nokia 600, 700 and 701 are all full-touchscreen devices without hardware keyboards. The 600 is billed as the “loudest smartphone,” catering to the music crowd with a small, but powerful, loudspeaker. Nokia’s “smallest smartphone” is the 700, with dimensions of 110 x 50.7 x 9.7 mm and a weight of just 96 g. Rounding out the trio is the new 701, which offers higher-end components than the others: a 1 GHz processor, 8-megapixel camera and more internal storage.
