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.
