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.
