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.

We start this week's edition of The Fonecast with a new product from RIM: the mobile-enabled BlackBerry PlayBook. Next comes Vodafone's move to Tech City and Google moving its mobile wallet into the cloud.

You'll also find the latest batch of quarterly results, some mobile data research and a story about sheep sending SMS text messages.

By now, everyone who's anyone has offered an online 'unboxing' of their Asus Google Nexus 7. And if they haven't, there's probably a review on the way.

Internet veteran Yahoo! provided last week’s biggest news, at least in terms of press coverage. It appointed Marissa Mayer as its President and Chief Executive Officer, having enticed her away from Google after 13 years.

It's a good week for Yahoo! as it appoints Marissa Mayer - previously Google employee number 20 - to the role of CEO. However, things aren't as cheery at Research In Motion, which has been ordered to pay over $147 million in a patent case.

Meanwhile O2 UK is recovering from a network problem that left around a third of its customers disconnected for almost a day.
