Last week a major retailer with a significant online presence announced plans to release its own-brand smartphone by the end of the year. No, not Amazon. This news came from Tesco.

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.

We have something for everyone in this week's podcast. There's bad news as Samba Mobile closes, bad news as Apple and Samsung suffer product faults... and bad news as wearable devices are criticised for the poor user experience they offer.

Yet there's plenty of good news as well, including the launch of a new UK mobile payment service.

Telefonica sets up its own mobile advertising business, Mozilla puts an interim CEO in place and Nokia suspends sales of its flagship Windows 8.1 RT tablet: all topics for discussion in this week's podcast.

We're also talking about the future growth of Orange Money, EE's online activity, mobile broadband growth and the Loch Ness monster being spotted on Apple iPhones.

This week's podcast starts with news from Microsoft about an update to its Windows Phone platform and a cost-free OS offer to hardware manufacturers.

There's also a new flagship smartphone from Nokia, a roaming announcement from the European Parliament, a UK virtual mobile network from The Co-operative Group, a change at the top for Mozilla, retail expansion for Vodafone and an awkward end to BlackBerry's relationship with T-Mobile in the USA.
