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.

Recent figures released by ABI Research have prompted the market intelligence company to ask whether Google is losing control of the Android ecosystem.

At first glance, Android dominated smartphone shipments for the final quarter of 2013. ABI Research says 77% of the 287 million smartphones shipped in Q4 2013 were running Android.

After initially suffering from slow pick up by consumers, 4G has begun to accelerate, and is now well on the way to the forecasted one billion subscribers by 2017. In fact EE, owner of T-Mobile and Orange, recently announced the addition of 493,000 new 4G customers to its existing base of 1.2 million.

A new report has highlighted the issue of poor mobile phone coverage in rural Sussex villages. BBC Sussex invited me onto their ‘Sussex Breakfast’ radio show to explain what could be done - and, as usual, I made enough notes for a lecture rather than a three-minute interview.

Here’s what I would have liked to have said if I’d been given a disproportionate amount of time to talk.

Great news for mobile phone users. Ofcom’s new rules preventing unexpected mid-contract price rises came into force last week, which means UK consumers can no longer be surprised by their subscription charge increasing while they’re still locked into a minimum-term deal.

This week, new Ofcom rules came into force. They’re designed to avoid unexpected price rises during the minimum term of a mobile phone contract. Yes, just because you signed a fixed-term contract doesn’t mean the charges can’t increase. Networks said they needed this option in case of inflation or regulatory changes. Customers felt trapped.

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.
