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.

By incorporating advanced algorithms and machine learning capabilities, AI can help to optimize a smartphone's performance, providing users with a faster, more efficient and user-friendly experience.

I've been taking a look back at the devices I've written about during the past few years. Some are still faithful companions, others... well, let's just say my faith was misplaced.

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. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?

This is part 2 of Mobile, Maps & Geolocation - so much more than "Where am I?"

It's a Mobile Monday London panel discussion with Gary Gale, Christopher Osborne, Jeni Tennison, Ian Holt and Harry Wood. Part 1 is available as a separate podcast.

This week's Mobile Monday London event featured a panel discussion about the opportunities for mobile-based geolocation and mapping. The event was supported by UK mapping agency Ordnance Survey.

In this podcast you'll hear the first part of the evening's discussion plus interviews with Nokia's Gary Gale, who chaired the panel, and Ian Holt from Ordnance Survey. Part 2 is available as a separate podcast.

This week's podcast starts with the world's slimmest smartphone (at least for the moment) before introducing a new smartphone company and even more new products from Samsung.

We're also talking about the battle of Instagram vs Vine, the sale of O2 Ireland, mobile retail web usage, the new CEO of BT and a new report about an unexpected health threat to mobile phone users.

Samsung has put a 10x optical zoom lens on a smartphone, Google is acquiring navigation app Waze and the European Commission is getting ready to equip cars with an emergency call system.

We're also talking about a strike threat at O2, the risk of 'showrooming' to high-street retailers, the end of Symbian smartphones and plenty more as well.

We start this week's podcast with Apple's announcement about the new version of its iOS platform - and follow this with a look at the privacy concerns surrounding the US government's PRISM operation.

Next come Samsung's new phones, Ericsson's new contract, a potential end to European roaming charges, some sophisticated mobile malware and plenty of other news stories as well.
