Finnish mobile company Jolla says it has completed its latest investment round and has secured new financing for the company.

It follows an announcement in November, when co-founder Antti Saarnio described the company as being in a “death valley”.

Finnish mobile company Jolla says it is adjusting its operations and will temporarily lay off what it describes as “a big part” of its personnel from next month.

The business, formed four years ago, developed the Sailfish mobile operating system and two associated products: the Jolla smartphone (launched in 2013) and the Jolla Tablet (launched last year).

We begin this week's podcast with updates on two topics we discussed last week: the potential purchase of a UK mobile network by BT - and the crowd-funded Jolla Tablet.

After that we talk about the GSMA's reaction to national roaming, the potential death of the landline, a new threat to Google, management changes and advertising for 4G data.

A crowd-funded campaign by Finnish mobile company Jolla to produce a new tablet device has raised more than three times as much money as it needed.

As a result, the company is planning to add the option of 3G HSDPA mobile data connectivity to the forthcoming Jolla Tablet. In addition, it’ll introduce a split-screen user interface and the ability to handle MicroSDHC memory cards of up to 128GB.

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 .

Mobile point of sale transactions (mPOS) are growing in popularity as mobile use takes over from desktop computers. The description of ‘mobile’ point of sale transactions denotes the ability of a payment to be taken via smartphone or tablet rather than a traditional card reader. There are many different ways to do this; mobile chip & PIN, mobile swipe & sign and NFC payments. All of these methods vary in popularity and security conceptions and many are difficult to understand. In this article we will explore each and give you the chance to understand the technology and issues surrounding the various methods.

The future of mobile technology is inextricably linked with video… or is it the other way round?

Some of the answers will be discussed next week at a seminar being run by the Digital TV Group (DTG), which is the industry association for digital television in the UK.

We started last week with a change of plan from BlackBerry. No, it’s not selling itself to Fairfax Financial. Instead it’s aiming to raise $1 billion from investors. Cynics might suggest there wasn’t enough interest for a takeover.

The Rockstar Consortium. That name sounds as though it could be promising more than it can deliver, doesn’t it?  Well, it’s not. It’s the group of mobile companies that picked up Nortel’s portfolio of several thousand tech patents for $4.5 billion. And now, its members – including Apple, Microsoft, BlackBerry, Ericsson and Sony – have set some of those patents on their biggest competitors.

No prizes for guessing which two mobile tech stories grabbed most of the headlines last week. Tuesday morning saw Nokia’s much-rumoured tablet and phablet launches, with a Windows RT device and two 6-inch smartphones joining the company’s product portfolio.

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.
