The new Apple iPad tablets, Google's latest Nexus devices, Android Lollipop, wearable tech from will.i.am and the world's slimmest smartphone all feature in this week's podcast.

We're also talking about free mobile data for Christmas, 4.5G technology being rolled out in the UK, 5G technology being tested in South Korea, the end of an era for webOS and video messages that self-destruct.

There are many mobile boundaries being blurred in this week's podcast.

Topics include Truphone's combined WiFi and mobile service, Skype's move to direct mobile billing, the rise of 4G and an Android-controlled satellite.

Mobile networks aren’t what they used to be. As last week’s interview with Vince Russell of The Cloud demonstrated, more and more customers are relying on WiFi to augment their mobile data service.

Truphone is now planning to do exactly the same with voice calls and text messages by linking its mobile network with WiFi for even wider coverage.

Voice over IP service Skype has announced the first countries where customers will be able to use its direct mobile operator billing option. This will let customers pay for Skype credit by charging it to their mobile phone account.

The facility has just been launched in Russia and will soon be enabled in the USA and Canada as well.

We’re moving into that time of year where product announcements are replaced by promotional campaigns and sales figures. Apple revealed it had sold three million assorted iPad tablets in just three days, while Samsung said its Galaxy SIII smartphone had sold more than 30 million units since its launch in May.

Mark Bridge writes:

It’s the telecoms industry deal of the year. T-Mobile and Orange form a joint venture. The UK’s "big five" networks (or "big four", depending on your predilection for Hutchison 3G UK) will now be a "big four" (or "big three", if you don’t include 3. Confused yet?)

Everyone has an opinion. On Tuesday I was asked for mine.

Mark Bridge writes:

Once upon a time, I’d probably have described myself as a feminist. These days I probably wouldn’t. Not because my opinions have changed, just because I’ve realised there are a lot of women who’d argue that I can’t be a feminist because of my male undercarriage. And me, by birth and possibly by education, therefore being part of the problem – not part of the solution.

Right, disclaimer over. I’ll get to the point. You want a mobile phone that’ll appeal to men...

Mobile phones fry your brain. That’s been a warning from some people pretty much since the first cellphones appeared. And although the mobile phone industry has changed and the technology has advanced, the warnings haven’t gone away.

Ten years ago, the Independent Expert Group on Mobile Phones was set up to look at concerns about the possible health effects from the use of mobile phones, base stations and transmitters.

Mark Bridge writes:

Enthusiasm is one of the great intangible powers of the world. It’s attractive, it’s compelling and sometimes it’s dangerous. And – yes, I’m going to try to keep this relevant – it sells mobile phones.

I was reminded of this the other day when I read a Sunday Times article about Apple’s Steve Jobs.

Marketing, not unlike football, is a funny old game. I don’t claim to be an expert in either… but every so often something happens that starts sowing the seeds of doubt in my mind. And no, I’m not thinking about Liverpool's penalty claims in Sunday’s game at Tottenham. I’m thinking about Blyk.

Here at The Fonecast, we like Blyk. They shook up the industry and worried some of the big names when they arrived with their youth-focussed virtual mobile network two years ago. We interviewed their MD Shaun Gregory in May last year. And now they’re quitting the MVNO game in favour of arranging advertising deals for networks.

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.
