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.

There are bad weeks... and there are BAD weeks. Blackberry had one of the latter. It all started so well. The company announced a new flagship phablet – the Z30 – and said it would be launching its BBM instant messaging service for iOS and Android handsets at the weekend.

We start this week's show with news about the European Commission's plans to end mobile roaming charges completely from next year.

We're also talking about the future facing Twitter and Dell, Vodafone's security challenges in Germany, app development, wireless charging, mobile payments and Nokia's Android-based smartphones.

There's good news for Telefonica as it's chosen to support the UK's smart meter rollout - but bad news for fans of the Microsoft Tag barcode, which is being discontinued in a couple of years' time.

We're also talking about drivers who use mobile phones illegally, Amazon's new service for mobile developers, the forthcoming Kazam smartphone, mobile advertising, satellite broadband, wearable security accessories and a word that's completely unacceptable to Motorola.

We start this week's podcast by talking about an Android security risk - before moving on to new 4G services from EE, a drop in Nook tablet prices and a couple of quarterly results that disappointed the stock market.

In addition we discuss insurance complaints, Bluetooth Smart technology, a new multi-million investment in Shazam and some research about the future of apps.
