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.

Mobile ticket and payment specialist Masabi has appointed Brian Zanghi as its Chief Executive Officer and President. He replaces co-founder Ben Whitaker, who will remain with the company as its new Head of Innovation.

Masabi is best known for the mobile ticketing solution it supplies to railways in the UK and the USA.

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.

Mobile ticketing is coming to river buses in London, enabling customers to pay for their trip via any compatible smartphone.

Thames Clippers, which runs boat services that serve around three million commuters and visitors every year, has signed a five-year agreement with London-based Masabi.

Mobile transport ticketing specialist Masabi has developed an all-in-one ticket app for rail operator First Great Western.

Customers can download the mobile application to a compatible smartphone or tablet and buy tickets for use with any UK train operator.

Mark Windle, head of marketing at OpenCloud, predicts that this year’s reduction in the number of traditional telecoms operators in some countries will provide an opportunity for other operators to innovate and capture market share in 2016.

He says next year will be a year of rapid change for telecoms… whether it’s MVNO disruption, competitive tariff pricing or simply defence from the ‘dark art’ of hacking.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?
