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.

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.
