Tech retailer Dixons Carphone plc - the company behind the Currys PC World and Carphone Warehouse brands in the UK - has announced plans to 'streamline' its store management, with up to 800 jobs expected to be cut across shops in the UK and Ireland.

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.

John Allan, one of two deputy chairmen at Dixons Carphone, has resigned from his post to take the job of chairman at Tesco plc.

Richard Broadbent, the current chairman of Tesco, is stepping down from the board on 1st March.

The Dixons Carphone Group, formed last summer when Dixons Retail and Carphone Warehouse merged, says it’ll launch a virtual mobile network this spring in partnership with Three UK.

The MVNO deal promises “innovative and highly personalised connectivity options”, according to the company.

Dixons Carphone, EE and Vodafone have all offered roles to a number of staff affected by the closure of Phones 4u stores.

Over 5,500 staff worked for the retailer when it went into administration last week.

Mark Windle, head of marketing at OpenCloud, predicts that this year’s reduction in the number of traditional telecoms operators in some countries will provide an opportunity for other operators to innovate and capture market share in 2016.

He says next year will be a year of rapid change for telecoms… whether it’s MVNO disruption, competitive tariff pricing or simply defence from the ‘dark art’ of hacking.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website.
