Samsung has announced that it’s the first smartphone provider accredited for joyn ‘Blackbird’.

Blackbird is the latest version of the GSMA’s joyn service, which was launched in 2012.

Libon, the Orange mobile app that offers free VoIP calls along with messaging and voicemail, has now been launched on Android. The iOS version of the app was released last year.

Both apps are available in the UK to customers on any network.

In this week's podcast we find BlackBerry facing a legal battle, SMS spammers suffering a big fine and EE boosting its 4G data tariffs.

We're also talking about a new iPhone camera accessory from musician will.i.am, rich cross-network communications in Spain, free WiFi in Yorkshire and the year's most-popular mobile search terms.

As the end of the year approaches, so the volume of ‘real news’ tends to reduce as it’s replaced by annual reviews and seasonal surveys. We’ll be joining in with our predictions for 2013 in a few weeks’ time... but first, here’s a look back at the biggest stories from the past seven days.

Spain’s three main mobile network operators - Movistar, Orange and Vodafone - have each launched Rich Communication Services (RCS) through the GSMA’s consumer-facing joyn brand.

It means that Spain has become the first country to offer this type of cross-network rich communications solution to mobile phone users.

A suggestion that UK mobile phone networks might be forced to improve black-spot coverage by allowing interconnection with their rivals is back in the news. It made the headlines in June and has returned again this week, which is why I could be heard offering my opinion on BBC local radio yesterday morning.

If I'm interviewing someone for a podcast, I'll generally use my Zoom H4N recorder and a separate microphone or two. But I don't need the same level of high-quality kit if I'm interviewing someone for a written interview. Why carry an expensive recording device when your mobile phone can do the same job?

Contactless payments. They're catching on, aren't they?

But mobile contactless payments haven't proved so popular.

I open the iPhone 6 box and discover a phone that feels substantial. Well engineered. Practical. Despite being just 6.9mm deep, it doesn't seem unreasonably delicate.

Following my online rant about the customer service I'd received when I suffered a problem with my HTC One, I wrote to Carphone Warehouse.

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.
