Lenovo has admitted that it’s been shipping laptops and convertible laptop/tablet devices with a security vulnerability.

Between September and December last year, Windows-based laptops from Lenovo were loaded with software called Superfish. This ‘broke’ secure web pages, which meant that any fraudulent secure sites wouldn’t be detected.

UK virtual mobile network giffgaff’s attempts to target its humorous horror-themed video ads have fallen foul of the Advertising Standards Authority.

The ASA received a complaint about a giffgaff advertisement on YouTube, which began with a screaming woman being pursued by a man who appeared to be holding a chainsaw.

Vodafone has signed a 15-year agreement with outdoor advertising company JCDecaux to deploy ‘small cells’ on street furniture and billboards, which will improve network performance.

It’s a global deal that follows a successful pilot programme where Vodafone Netherlands installed over 160 small cells on bus shelters in Amsterdam.

We begin this week's podcast with updates on two topics we discussed last week: the potential purchase of a UK mobile network by BT - and the crowd-funded Jolla Tablet.

After that we talk about the GSMA's reaction to national roaming, the potential death of the landline, a new threat to Google, management changes and advertising for 4G data.

The Advertising Standards Authority has upheld complaints about a promotional message from UK virtual network Lycamobile.

A link on Lycamobile’s web site referred to “Unlimited Data, now with 4G”, while an advertisement on the site said “£15 per month ... unlimited data now with 4G”.

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.
