Carphone Warehouse has completed its planned acquisition of Best Buy’s 50% share of the CPW Europe business, bringing an end to the joint retail venture.

From next month’s AGM, Andrew Harrison is stepping up to become CEO of the Carphone Warehouse Group. Roger Taylor, current Group CEO, will become deputy chairman.

Carphone Warehouse is planning to take over the European business that bears its name, which is actually a 50/50 joint venture set up with US-based retailer Best Buy in June 2008. It’s agreed to pay £471 million for the 50% of CPW Europe it doesn’t already own.

This 50% share in Carphone Warehouse was originally sold for around £1.1 billion as part of Best Buy’s European expansion.

American technology retailer Best Buy Co. Inc. has confirmed that it’s received a letter from Richard Schulze, the company’s founder and former chairman, outlining an offer to acquire all the Best Buy shares he doesn’t already own. Mr Schulze resigned as chairman in June this year.

His offer of $24 to $26 per share is significantly above the current trading price for the company’s shares, which are trading at around $20.

Carphone Warehouse Group plc has published a trading update for the fourth quarter of its financial year.

Revenue at CPW Europe - the company’s 50% joint venture with Best Buy - were down 5.5%, while total connections were down 19%. Postpay connections were up in the UK, although the company estimates that the overall prepay market in Q4 was down 30-40% in the UK.

The UK-based Mobile Money Network, which is behind the Simply Tap mobile shopping app, says Visa Europe is planning to take a 15% stake in its business. Visa Europe will join the MNN’s three founders: Monitise, Best Buy Europe and Charles Dunstone.

The two businesses aim to implement a number of m-commerce initiatives in the UK in 2012.

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?

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.
