In this week's podcast we talk about two of the big announcements from Google I/O: a new version of Android and the retail launch of smartwatches powered by 'Android Wear'.

We also talk about Android-based smartphones from Nokia and Blackphone, network complaints in the UK, a reduction in European roaming charges and mobile ticketing.

This week's podcast covers the launch of the first Amazon smartphone and the introduction of Google Glass to the UK.

We also talk about new WiFi-powered voice services from EE and Three, plans to reduce mobile 'black spots', BlackBerry's app partnership, smartphone theft, 4G innovation... and rechargeable trousers.

This week's podcast begins with Ofcom's plans to cut the wholesale cost of inter-network mobile phone calls. But what benefit will consumers see?

Iain, James and Mark then move on to discuss luxury smartphones, a new handset on the high street, mobile broadband for aircraft passengers, government monitoring, the growth of smartphones - and 4G-equipped donkeys.

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.

Mark Bridge writes:

“Hey, everybody, we’re releasing a new flagship smartphone that carries all the hopes of the company with it. If this sells well, we could be saved. If not, it could be disaster.”

“Great. What shall we call our new phone?”

“Oh, we’ll give it the same name as the previous model. That’ll be fine.”
