BT has responded to news reports about its possible acquisition of the O2 mobile network from Telefónica UK.

The speculation was first published on a website in Spain, with suggestions that Telefonica could receive a 20% share of BT as part of the multi-million pound deal.

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.

Telecoms business TalkTalk has set up a  new multi-year MVNO agreement with Telefónica UK, the company behind O2.

TalkTalk’s current virtual network agreement is with Vodafone.

We start this week's podcast with news that EE now has the largest 4G customer base in Europe, with 5.6 million UK connections.

There's also talk about a new DIY product for the Internet of Things, the disappearance of Nokia branded smartphones, quarterly results for Apple, increasing M2M connections and a growing market for smartwatches.

Telefónica, the company behind O2 in the UK, has launched an ‘Internet of Things’ product that enables consumers to monitor and control the temperature, humidity and lighting in their home or office.

It’s the first in a range of modular solutions called Thinking Things, which will let users develop their own ‘smart’ M2M solutions without any programming knowledge or the need to install additional infrastructure.
