Canonical, the company behind the Linux-based Ubuntu open-source platform, has announced what it’s calling “the world’s first Ubuntu phone”.

The Aquaris E4.5 Ubuntu Edition is being produced in partnership with Spanish electronics and software company BQ.

UK virtual mobile network giffgaff’s attempts to target its humorous horror-themed video ads have fallen foul of the Advertising Standards Authority.

The ASA received a complaint about a giffgaff advertisement on YouTube, which began with a screaming woman being pursued by a man who appeared to be holding a chainsaw.

In this week's podcast we're talking about the potential purchase of the O2 UK mobile network by BT.

We also discuss new tablets from Nokia and Jolla, the end of a patent battle, mobile payments via instant messaging, app development for the Apple Watch and plans to make even more spectrum available for mobile broadband in the UK .

A video advertisement from Telefonica-owned UK MVNO giffgaff was likely to cause serious or widespread offence, according to a ruling by the Advertising Standards Authority.

The video clip was promoted via giffgaff’s Twitter account, which was also available via an embedded feed on the giffgaff website. As well as showing a link to the video clip, the tweet said “The situations in our new videos are, well, awkward. #NSFW #alltheboss”.

This week my lovely wife made a rare error in leaving her mobile phone behind when she left the house. Fortunately I was working at home, so I was able to answer her calls and relay her messages. But it got me thinking. What were the alternatives?

We've had another short working week here in the UK... although not necessarily if you're working in retail. The reason for that shortness was a combination of Easter Monday and the Royal Wedding – an event that was rumoured to have its own mobile phone jammer.

As well as having another short week, we've also had another week of financial figures.

It’s Easter, but that’s not stopped the mobile phone industry from generating plenty of news stories.

Let’s start with partnerships. Deutsche Telekom and France Telecom - which already work together as Everything Everywhere in the UK – have now agreed to combine their procurement activities for customer equipment, network equipment, service platforms and IT infrastructure. Yes, even these two telecoms giants can save money with group buying!

In July last year I wrote about the 'geek porn' of unboxing being taken to a new level with celebrity unboxing (which sounds rather like a challenge from a reality TV show).

Sony Ericsson had persuaded Maria Sharapova to give her first impressions of the X10 Mini Pro. The end result was entertaining, if not insightful.

And now Samsung have added a new facet to the trend with 'extreme unboxing'.

We started this week with a story that grabbed plenty of attention. It was a report from Billmonitor.com that claimed we in the UK were wasting almost £5 billion every year by choosing the wrong mobile tariffs. Although I remained a little cynical about some of the detail, there's no doubt that many consumers could be better off if they switched tariff - or even network.

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.
