Facebook has announced its latest quarterly earnings figures and has also revealed details of the social network’s mobile-based users.

The number of monthly active users (MAUs) was up 15% year-on-year to 1.28 billion, with mobile MAUs up 34% to 1.01 billion.

We begin this week's podcast with a discussion about the Heartbleed bug, the effect it's having on the mobile industry and the wider issues for all internet users.

We're also talking about the future of BlackBerry, UK 4G coverage, new CEOs, Bluetooth connectivity, privacy concerns and the next generation of mobile processors.

Facebook and WhatsApp have received a letter from the US Federal Trade Commission reminding them about user privacy.

In February, Facebook announced that it was planning to acquire messaging service WhatsApp in a deal worth $16 billion (£9.6 billion).

Messaging was very much on the agenda at Mobile World Congress this year, following Facebook's announcement that it was planning to acquire WhatsApp in a 19 billion dollar deal. So if the future for this type of internet-based 'over the top' messaging service looks good, what does this mean for SMS?

To find out more, we spoke to Stacy Adams of mBlox to learn what was happening in the messaging world, to find out how SMS is being integrated with mobile apps - and to discover some of the other ways SMS was being used by businesses today.

This week's programme begins with some of the biggest news stories that came out of Mobile World Congress.

Iain, James and Mark then move on to the other headlines from the past few days, including Boeing's secret agent smartphone, Apple's plans for mobile in-car entertainment, a new structure for Telefonica and new technology for mobile payments.

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?

James Rosewell and Mark Bridge return from their summer break with a podcast full of smartphones and smart watches.

As well as products from Samsung, Sony, Microsoft, Motorola, HTC and Kazam, there's talk of Opera's new browser deal, a potential change on the UK high street... and a mobile app that connects to a Bluetooth toothbrush for improved toothpaste coverage.

Mark Bridge takes an in-depth look at the CAT B100 rugged phone from Bullitt Mobile.

The CAT B100 is designed to withstand rather more than everyday bumps and knocks - which is why Mark drops his mobile phone on the pavement, submerges it in his washing-up bowl and shuts it in the freezer.

We start this week's podcast with news that thousands of Microsoft's ex-Nokia employees are losing their jobs.

Other topics for discussion include the new Apple and IBM partnership, Yahoo's acquisition of Flurry, regulating mobile games, improving rural mobile coverage, BT's new phone service and some management movements.

In this podcast Mark Bridge talks to Florent Stroppa from mobile value-added service specialist OnMobile about the state of the mobile industry in 2014.

They discuss the dominance of Apple and Samsung, network consolidation, the new Amazon Fire smartphone, smart wearables and much more.

This week's mobile industry podcast begins with a quick look at the UK government's emergency legislation affecting fixed-line, mobile phone and broadband traffic.

We then talk about Microsoft's plans, a new virtual network from the Post Office, Samsung's renamed app store, budget 4G smartphones, a wearable phone for children and some misleading advertising.
