This week's edition of The Fonecast starts with news that Motorola Mobility is to lose around a fifth of its staff worldwide. There's also more reorganisation at Nokia, which is passing its Qt software business to Digia.

In addition we're talking about a new US partnership between Starbucks and Square, some good news for Research In Motion, a worrying report for Samsung and a major milestone for Shazam.

Last year Finnish software company Digia arranged to acquire the Qt commercial software licensing business from Nokia.

It’s now announced plans to acquire the Qt technology and business from Nokia, which means it’s taking over the entire Qt Project. Digia now plans to bring Qt to the Android, iOS and Windows 8 platforms.

Nokia's Qt application and user interface framework business unit, which enables software to be deployed across different platforms without rewriting the source code, is being split. Nokia will continue to invest in the development of Qt for all users, while Finnish company Digia will acquire the Qt commercial software licensing and professional services business.

Qt is available under open source licenses and a commercial license.

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.
