We start this week's podcast with Tesco's plans for a Hudl-branded smartphone. Next comes some potentially good news about the 'patent wars' affecting the mobile industry - although there's certainly no sign of a ceasefire.

Later we discuss an announcement from Facebook about its mobile advertising scheme, an unfortunate mistake for O2's Travel service, a new 20 megapixel camera-phone and an automotive investment by Nokia.

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.

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.

Even at Mobile World Congress, the relevance of the mobile network operator can sometimes be forgotten. So for a different perspective on this year's event, we spoke to Samuel Johnston from British mobile crowd-sourcing firm OpenSignal.

Samuel discussed the announcements from MWC14 and OpenSignal's latest report into 4G LTE coverage around the world, as well as giving us an exclusive insight into OpenSignal's next research subject.

This podcast takes a look at the issue of finance for start-ups - and, in particular, at Accelerators for tech-based companies.

It's a discussion that was recorded at Mobile Monday London earlier this week with a panel including Jon Bradford of Techstars, Simon Devonshire from Telefonica's Wayra, Diane Perlman from Microsoft Ventures and Simon Cook of DFJ Esprit.
