We begin this week's podcast with updates on two topics we discussed last week: the potential purchase of a UK mobile network by BT - and the crowd-funded Jolla Tablet.

After that we talk about the GSMA's reaction to national roaming, the potential death of the landline, a new threat to Google, management changes and advertising for 4G data.

In this week's podcast we're talking about the potential purchase of the O2 UK mobile network by BT.

We also discuss new tablets from Nokia and Jolla, the end of a patent battle, mobile payments via instant messaging, app development for the Apple Watch and plans to make even more spectrum available for mobile broadband in the UK .

It's been a week of diverse mobile headlines in which Jolla started selling its Sailfish smartphone, mobile shopping broke records and BlackBerry's CEO looked to the future.

We're also talking about smartphones for seniors, battery life, a looming spectrum shortage, phone theft and Sony's Smart Wig. Something for everyone, surely!

We start this week's podcast by talking about Yahoo and Tumblr before moving on to discuss Google's recent developer conference.

There are product announcements from BlackBerry, HP and the former MeeGo developers at Jolla... and there's some interesting mobile app news as well.

There's plenty of variety in The Fonecast this week. We start the podcast with news of MeeGo's resurrection by Finnish smartphone company Jolla before talking about a mobile network that’s giving away mobile data whenever its customers watch video advertisements.

There's also time to discuss Telefonica's recent deals, the rise of free WiFi availability, tablet-related legal action, malware in the Apple App Store and the truth behind a recent 'exploding mobile phone' story.
