We start this week with a look at troubled UK retailer HMV before moving on to research that sheds new light on mobile data usage.

You'll also find a new mapping app, increasing free WiFi coverage, a phone service designed for children and preliminary quarterly results from Samsung and Nokia.

Oh, how the mobile industry loves a superlative. Much like the work ethic celebrated by Daft Punk (or Kanye West, if you prefer), it’s always looking for a new angle.

NTT Docomo says it’s working on a mobile phone that’s aimed specifically at pre-teen children and teenagers who are upper elementary and junior high school students in Japan.

The Smartphone for Juniors SH-05E is being manufactured by Sharp and will go on sale in early February.

Seven major mobile network operators - KPN, NTT DOCOMO, Rogers, SingTel, Telefónica, Telstra and Vimpelcom - have formed an alliance that’ll see them working together on machine-to-machine (M2M) projects.

The initiative is also open to other operators.

It’s time for my summary of last week’s mobile industry news… and what a week it’s been. Not just for me – I made my first-ever visit to Over The Air on Friday – but for the world of mobile devices.

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?

In this week's podcast we find BlackBerry facing a legal battle, SMS spammers suffering a big fine and EE boosting its 4G data tariffs.

We're also talking about a new iPhone camera accessory from musician will.i.am, rich cross-network communications in Spain, free WiFi in Yorkshire and the year's most-popular mobile search terms.

This week's podcast starts with news that HP is unhappy - but we resist the temptation to include any saucy puns that might spice up the story.

The programme also covers Nokia's new Facebook-friendly phone, plans for white space technology in the UK, shopping on smartphones, Samsung's Chinese suppliers, the demand for mobile data and a new app from Orange that seems to threaten its mobile business.

There's plenty of talk about mobile networks in this week's podcast. We start with a new charity-focussed MVNO before moving on to Ofcom's plans for avoiding a mobile capacity crunch.

There's also talk about WiFi offloading, BlackBerry's free voice calling service, Nokia's map business and much more as well.

In this special feature we're talking about mobile marketing and consumer privacy with Henry Lawson, CEO and co-founder of nFluence.

nFluence offers a technology solution that lets customers use their smartphone to personalise their marketing preferences in less than 30 seconds.

The UK's 4G spectrum auctions are given a start date, while RIM reveals the launch day for its BlackBerry 10 platform.
