Voice over IP – the ability to make phone calls over the internet - is a topic we covered in our first-ever podcast five years ago. At times it promised to change the way we used mobile phones... so what's been happening?

I've been talking to Tanveer Sharif, CEO and co-founder of international call service Vopium, to learn more.

Having just returned from a week's holiday in a part of the country where mobile coverage was surprisingly sparse, it struck me how much mobile phones were linked to the recent English riots and looting.

A mobile phone case is often seen simply as a revenue opportunity for retailers. But, as you might expect, there's a lot more to this type of accessory than first meets the eye.

I started this week's podcast feature by asking Rhona Cashman from protective case manufacturer OtterBox why mobile phone dealers should be discerning about the cases they sell.

David Drummond, Google's Senior Vice President and Chief Legal Officer, has just written a blog post that describes an 'anti-competitive strategy' against Android by companies including Apple, Microsoft and Oracle. Entitled "When patents attack Android", it points out that more than 550,000 Android devices are now activated every day... and says this has resulted in "a hostile, organized campaign against Android".

Last month, News Corporation's Rupert Murdoch said the News of the World had accounted for just 1% of his global business. It's a figure that put the overall size of News Corp into perspective.

This week, some analysis of Microsoft's financial results seems to suggest Windows Phone is only generating a similarly small percentage for its parent.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
