Nokia has announced a new Symbian smartphone today: the Nokia 500.

It's a touchscreen device with a 1GHz processor running the Symbian Anna operating system. As well as having a name that doesn't fit with the previous E, N, C and X prefixes, the Nokia 500 is also notable for weighing just 93g – less than any other Symbian^3 device.

This week's edition of The Fonecast covers a wide range of subjects from within the mobile industry. We start with Symbian before moving on to 'white space' spectrum trials involving BT, the BBC, Samsung and Nokia. There's also time to talk about funding, favourite apps, legal action and some notable moves.

The GSMA and comScore have just released data showing how UK mobile consumers use mobile applications. The data has been collected in partnership with mobile networks and is the latest in the GSMA Mobile Media Metrics series of reports.

Overall, almost 8.8 million UK mobile phone owners - 40% of the UK's mobile internet users - accessed an app that connected to the internet during April 2011.

Last month Nokia CEO Stephen Elop said that software support for Symbian phones would continue until 2016 at the earliest. It's now become clear why he was able to give that date with such confidence.

Nokia and Accenture have published details of their agreement for the outsourcing of Symbian software development and support activities, which was first announced at the end of April.
