Time for another podcast presented by Iain Graham, James Rosewell and Mark Bridge. They begin this week's programme by talking about the latest enterprise-friendly developments from BlackBerry.

Next comes a new survey from Ofcom about the UK's 4G data speeds, followed by news about TalkTalk's MVNO deal with Telefonica, the growth of WiFi in the home and a report from AVG about social media sapping smartphone performance.

A new report from online security company AVG Technologies says social media is often to blame for affecting smartphone battery life and other performance factors.

Its latest Android App Performance Report is based on an analysis of anonymous data from over one million AVG Android app users around the world, listing the top apps that affect data consumption, storage capacity and battery life.

After three years at the top of the Millward Brown BrandZ Top 100 Most Valuable Brands chart, Apple has lost the number 1 position to Google.

Apple slipped to second place in 2014, whilst IBM remained in third.

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.

Facebook has launched a mobile advertising network at its F8 developers conference, giving app developers a new option for monetising their applications.

The Facebook Audience Network offers the same level of targeting as Facebook’s browser-based ads.

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.

Mark Bridge writes:

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?

We're in Barcelona for the GSMA Mobile World Congress 2011. Here's our report at the beginning of the final day, with James talking about the MeeGo and webOS platforms... and Mark reporting on new products from ViewSonic and Motorola Mobility.

We're in Barcelona for the GSMA Mobile World Congress 2011. Here's our report at the beginning of day three, talking about personal privacy in the mobile age. Contributions come from Qualcomm, Eric Schmidt of Google and the Mobile Marketing Association.

We're in Barcelona for the GSMA Mobile World Congress 2011. Here's our report at the beginning of day two, covering everything from LG's 3D mobile phone and MACH's innovative roaming billing to Steve Ballmer's keynote speech.

We're in Barcelona for the GSMA Mobile World Congress 2011. It starts today - but Sony Ericsson, Samsung and Nokia all held press events on the previous evening. We cover the big announcements and also pay a visit to the ShowStoppers showcase.

This week's podcast sets the scene for Mobile World Congress, with mobile payments, mobile applications, the PlayStation Phone and Nokia's future all up for discussion. There's also an interview with Dr Windsor Holden of Juniper Research about the trends and products to watch for when the industry heads to Barcelona.
