In this week's show we look at Google's new product announcements, O2's closure of its mobile telecare service and the clearance of radio frequencies for 4G services.

We also talk about the latest collection of quarterly results from Apple, Samsung, Amazon, LG and Facebook. Who's doing well - and should anyone be worried?

We start this week's show by discussing the recent quarterly results from Google, Nokia, Vodafone and Microsoft.

There's also time to talk about SIM security, Ubuntu's crowd-funded smartphone, the HTC One mini, smart watches and an unusual process for recharging your phone battery.

In our podcast this week we're discussing the new SmartWatch from Sony, talking about Firefox OS smartphones and contemplating Vodafone's partnership with Sainsbury's.

We're also looking at complaint figures, roaming charges, pay as you go pricing, joint ventures, BlackBerry's recent results and the future of Windows Phone.

This week's podcast starts with the world's slimmest smartphone (at least for the moment) before introducing a new smartphone company and even more new products from Samsung.

We're also talking about the battle of Instagram vs Vine, the sale of O2 Ireland, mobile retail web usage, the new CEO of BT and a new report about an unexpected health threat to mobile phone users.

This week's podcast begins with a report about a delay - or perhaps even cancellation - for the UK launch of HTC's Facebook phone, the HTC First.

We then move on to Vodafone's results, an Android app scare for Sky, Samsung's successes, contactless payments, potentially life-saving QR codes and an uncomfortable story about a smuggled mobile phone.
