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?

Text messaging remains a popular way for businesses to keep in touch with staff and customers - despite the appearance of newer, more sophisticated services. Geoff Love of Esendex explains the appeal of SMS messaging.

We start this week with two big handset stories - BlackBerry 10 and the Samsung Galaxy S3 - before moving on to the rest of the news, including more mobile wallets, more free WiFi, more quarterly results and more legal action!

A number of familiar topics return to the headlines this week. Alongside mobile health concerns and mobile wallets, there's also news about 'white space' developments and a new leader in mobile phone manufacturing.

This week's podcast starts with Nokia's billion-pound loss, although there's plenty of good news as well. We discuss it all - from UK ad-funded network Ovivo Mobile to Barclaycard's new spin on mobile payments.
