Nokia has announced the N8 smartphone, which is set to be the first device running version 3 of the Symbian operating system. There’s a 12 megapixel camera with Xenon flash, there’s HD-quality video recording, Dolby surround sound and a 3.5-inch organic LED screen in the aluminium body.

There's also social network aggregation, built-in video editing and the free Ovi Maps navigation service. Symbian ^3 includes support for multi-touch, flick scrolling and pinch-zoom on the touchscreen.

Research In Motion Limited has announced a new service called BlackBerry Mobile Voice System 5, which will offer voice-over-WiFi calling from later this year. BlackBerry MVS 5 works with Cisco Unified Communications Manager to provide a business user with the ability to use their regular fixed-line office telephone number and extension from their BlackBerry device. It means businesses can let their staff receive calls on their regular office phone numbers whenever they're connected to a WiFi network.

Calls made through BlackBerry MVS 5 are routed through the company's Private Branch Exchange (PBX) system. Employees also benefit from the convenience of a single work phone number shared between their desk phone and BlackBerry smartphone. Incoming calls can ring simultaneously on the employee’s desk phone and their BlackBerry.
