Earlier this year, figures from RAJAR Ltd (Radio Joint Audience Research) showed that 13% of UK adults had listened to the radio via mobile phone. 54% of these selected the station using an FM preset, while 14% ran an app for a specific radio station.

Now, new research has revealed that 20% of smartphone owners - 1.4 million people – have downloaded a radio app, with over half of them (53%) using the application at least once a week. These figures are part of RAJAR's latest MIDAS (Measurement of Internet Delivered Audio Services) survey.

Telefónica Europe, which bought mobile VoIP company JAJAH in December, has started rolling-out JAJAH-powered IP-based phone services across its O2 businesses in Europe.

The first is international calling service O2 Global Friends, which lets customers in Germany make international calls by dialling a dedicated local number. The call is then routed over the internet without the need for any software downloads or new hardware.

Vodafone, which bought navigation service Wayfinder in early 2009 and closed it down just over a year later, is now giving away the software. Wayfinder's location and navigation software can now be found on github.com and via Vodafone’s open source portal at www.betavine.net.

A report from ABI Research expects that Linux-based operating systems – including Google’s Android and forthcoming Chrome OS - will comprise 62% of operating systems shipped in all non-smartphone mobile devices by 2015. Other Linux-based systems include MeeGo and the Palm webOS.
