Telefonica sets up its own mobile advertising business, Mozilla puts an interim CEO in place and Nokia suspends sales of its flagship Windows 8.1 RT tablet: all topics for discussion in this week's podcast.

We're also talking about the future growth of Orange Money, EE's online activity, mobile broadband growth and the Loch Ness monster being spotted on Apple iPhones.

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.

Producing mobile phones for older customers requires much more than big buttons and a simple interface. At Mobile World Congress last month we spoke to two major players in this growing sector: Swedish company Doro and Austria's Emporia Telecom.

Our first conversation was with Harald Obereder, Chief Technology Officer at Emporia, who spoke to Mark Bridge about handset design and user interface design. This was followed by an interview with Chris Millington, Managing Director for Doro UK and Ireland, about research and development in the 'senior tech' market.

We begin this week's programme by looking at Vodafone's acquisition plans in Spain before moving on to discuss universal mobile chargers and 4G roaming.

There's also time to talk about UK mobile coverage, EE's new customer tracking service, contactless transactions and a smartphone camera that can identify objects hidden behind something else.

We start this week's report with two new smartphones: a flagship Android device from LG and a dual-boot handset from Geeksphone.

We also talk about the health effects of mobile phones, a new mobile loyalty app, wireless charging, machine-to-machine connections, the purchase of Viber and a recent acquisition by Google.
