A new report from mobile analysts at Juniper Research estimates that 320.3 million smartphones were shipped worldwide in the first quarter of this year.

That's a year-on-year drop of almost 6%.

Sony Mobile Communications has updated its Xperia brand with three new X-series smartphones: the lower-spec Xperia XA, the Xperia X and the premium Xperia X Performance.

All have an improved camera with ‘Predictive Hybrid Autofocus’, which is capable of tracking moving objects.

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.

The ‘explorer edition’ of Google Glass was discontinued earlier this year - but now Sony has stepped into the market, releasing a ‘developer edition’ of the Sony SmartEyeglass.

It’ll cost £620 and is already available to order in the UK, with availability expected from March.

Sony has announced a collection of new devices at the IFA consumer electronics show.

The Sony Xperia Z3 has a 5.2-inch display and a 20.7 megapixel camera. There’s also a smaller version, the Z3 Compact.

Live TV and radio interviews. They can be worrying things, even when you’re not expecting to be challenged too much. I know this from experience. So when your company is launching a much-delayed operating system, you’d expect a few difficult questions… and you’d be ready with a response.

The official response of RIM is apparently to ignore the questions.

Rene Mendy, a street vendor in Dakar, has never had enough money to open a bank account. But now, thanks to an emerging mobile phone banking service, he has access to many financial services.

I didn’t study economics at college, which is probably one of the reasons I have a very simple perspective on quarterly results. As far as I’m concerned, they fall into one of three categories: much as expected, better than expected or worse than expected. Anyway, it’s the time of year when some of the biggest names in the mobile telecoms industry publish their financial results – so here we go.

Targeted advertising on mobile devices is something we’re all getting increasingly familiar with. Visit a web site and there’s a good chance you’ll see an advertisement that’s aimed directly at you, perhaps using information about the sites you’ve previously visited, the type of smartphone you’re using or even your location.

Yet listen to the radio or stream music on your smartphone and that same level of personalisation hasn’t been aavailable. That’s all changing now, with help from a new service called UTuneMe.

Huawei is a company one can’t miss at Mobile World Congress. They bring their own building!  Plus last year a wonderful “Pegasus” flying horse sculpture made using Ascend handsets was proudly displayed next to the main fountain to hail the launch of the Ascend series of handsets.

Huawei has been busy following MWC12. They now run major parts of Everything Everywhere, Three and O2’s network in the UK. On a less positive note they’re not welcome in the US.

But how has the devices side of the business performed?

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.

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.
