After catching up with last week's Microsoft announcement about new CEO Satya Nadella, we go on to talk about big changes for Brightstar and Sony as well.

There's also mobile payment news from MasterCard and Weve, some patent agreements, a warning about second-hand smartphone sales, a forecast of mobile data growth and a report about app developers.

Product news in today's podcast includes Samsung's curved-screen smartphone, an HTC phablet and an update for Windows Phone 8.

We're also talking about malware, roaming charges, Ofcom's licence fees, a drop in mobile revenue, BT's MVNO and a project that sounds... well... silly.

There are big changes on the horizon at BlackBerry. We talk about the company's potential future and also look at the recent tablet announcements from Microsoft and Tesco... plus the rest of the week's mobile news.

There's also a special report from IAB2013 about the sometimes awkward relationship between mobile devices and the television industry.

We're back after a short break last week - and just in time for three of the biggest industry news stories of the year.

Microsoft's CEO announces his retirement, then Vodafone sells its US operation for $130 billion... and now Nokia's mobile phone business is being bought. Alongside these reports there's also time to talk about 4G in the UK, children with mobiles, roaming charges and the future of smartphones.

We start this week's show by discussing the recent quarterly results from Google, Nokia, Vodafone and Microsoft.

There's also time to talk about SIM security, Ubuntu's crowd-funded smartphone, the HTC One mini, smart watches and an unusual process for recharging your phone battery.
