This week's edition of The Fonecast starts with news that Motorola Mobility is to lose around a fifth of its staff worldwide. There's also more reorganisation at Nokia, which is passing its Qt software business to Digia.

In addition we're talking about a new US partnership between Starbucks and Square, some good news for Research In Motion, a worrying report for Samsung and a major milestone for Shazam.

Last year Finnish software company Digia arranged to acquire the Qt commercial software licensing business from Nokia.

It’s now announced plans to acquire the Qt technology and business from Nokia, which means it’s taking over the entire Qt Project. Digia now plans to bring Qt to the Android, iOS and Windows 8 platforms.

Nokia's Qt application and user interface framework business unit, which enables software to be deployed across different platforms without rewriting the source code, is being split. Nokia will continue to invest in the development of Qt for all users, while Finnish company Digia will acquire the Qt commercial software licensing and professional services business.

Qt is available under open source licenses and a commercial license.

Last week a major retailer with a significant online presence announced plans to release its own-brand smartphone by the end of the year. No, not Amazon. This news came from Tesco.

Lawrence Lundy of Frost & Sullivan writes:

While the Galaxy S5 is an evolutionary product, there is not enough in there to make people upgrade from the 4. It doesn't push the envelope in any real way; we are in a sort of stasis now when it comes to smartphone innovation.

The Smart City is on its way. All over the world more and more cities are connecting all areas of their infrastructure. Pisa in Tuscany, for example, aims to improve its traffic management with a machine-to-machine (M2M) solution and a Big Data service provided by Deutsche Telekom.

“Hey, everybody, we’re releasing a new flagship smartphone that carries all the hopes of the company with it. If this sells well, we could be saved. If not, it could be disaster.”

“Great. What shall we call our new phone?”

“Oh, we’ll give it the same name as the previous model. That’ll be fine.”

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.
