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?

This week's podcast begins with news about the new 'quad play' television service offered in the UK by EE.

We also talk about HTC's new camera, an ethical smartphone, a complaint from Ofcom, mobile payments, machine-to-machine connections and yet another online security breach.

We begin this week's podcast with stories that go beyond the mobile industry, as HP plans to split into two companies and eBay prepares to separate itself from PayPal.

We're also talking about the Microsoft/Samsung legal case, a new Tesco tablet, BT's updated text relay service, a new way to avoid buying a stolen iPhone... and #Hairgate.

In this week's podcast we begin with more news about Phones 4u, as Carphone Warehouse steps in to help iPhone 6 buyers.

We also talk about problems at Apple, a brand new handset from BlackBerry, mobile payments, phones on planes and a device that promises to stop people from texting while driving.

This week's podcast begins with the latest news from Phones 4u, where hundreds of jobs have been saved but there are a large number of redundancies as well.

Iain, James and Mark then talk about new products from Amazon, BlackBerry and Panasonic, mobile payment innovation from Indonesia and the UK, the acquisition of IoT specialist Neul and Apple's updated privacy policy.

Iain Graham, James Rosewell and Mark Bridge start this week's podcast by looking back at the launch of the iPhone 6, the Apple Watch and the Apple Pay service.

They then move on to discuss the troubles at Phones 4u, a UK smartphone launch from O2, another smartphone launch that's been put on hold, Microsoft's gaming plans - and more.
