Nokia World 2011: new lease of life for Symbian?

Nokia begins its annual Nokia World 2011 symposium in London tomorrow - the Finnish smartphone maker's forum for launching handsets and technology with its first Windows Phone 7.5 (WP7.5) handsets set to make an appearance. But perhaps the biggest surprise is a new lease of life for the company's seemingly doomed Symbian OS.

Nokia World began in 2006, the year that saw its groundbreaking N95 being launched in Amsterdam. Other notable launches at Nokia World include 2009's unveiling of the XpressMusic range of phones.

This year's star attraction will be the announcement of Nokia's first WP7.5 handsets, the fruit of a deal announced in February this year with Microsoft to see the software giant's Windows Phone 7.5 operating system deployed on Nokia handsets - the first time Nokia has ever created handsets for another company's OS.

But contrary to rumours, Nokia's own Symbian operating system isn't yet dead in the water, and will still be a feature of the event. As a source at the Finnish mobile maker told our friends at mobile news site OneMobileRing, more Symbian-based handsets will be coming out over the course of the next 12 months.

More information is also sure to be revealed about the roll-out of Nokia's latest Symbian 'Belle' platform, which is due to be deployed onto existing devices running the Symbian Anna operating system - replacing the Symbian^3 OS.

OneMobileRing will be live blogging from the opening keynote speech on Wednesday 26th October, so stay tuned for all the latest announcements from Nokia World 2011.
