The Open Mobile Summit will return to London for its fourth year next month, running from 29-30 May at the Victoria Park Plaza in London.

The two-day conference covers all aspects of mobile business, and includes panels on 4G technology, competing in the cloud, and mobile advertising.

What's the agenda?

There's a strong showing for mobile gaming this year, too, with speakers from Disney, Gameloft, Outfit7, MindCandy, Bottle Rocket, and Bionic Panda taking to the stage to share their wisdom.

Of particular relevance to mobile games is the 'Entertainment brands: From Mickey Mouse to Angry Birds' panel, which sees MindCandy CEO Michael Acton Smith, Outfit7 CEO Samo Login, Gameloft SVP Gonzague de Vallois, and Disney's VP and GM of digital games Jeff Jones discuss app monetisation, branding, and partnerships with established media.

Registration is open now, and earlybird pricing is available on conference passes until 5 April.
