We start this week's edition of The Fonecast with confirmation that 4G coverage will be launched in the UK this year, thanks to Everything Everywhere.

However, all's not well in the world of mobile retail - as mystery shopping by a consumer organisation reports widespread misinformation from sales staff.

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.

There are plenty of quarterly results to report in this week's edition of The Fonecast, including Samsung, Apple, Telefonica and Facebook. In addition, we have new research that shows how smartphone sales are racing ahead as feature phone sales slow down.

There's also news about mobile coverage in the Channel Tunnel, mobile application downloads and m-commerce.

In today's podcast we're talking to Doug Suriano, Chief Technology Officer at mobile broadband solutions company Tekelec, about net neutrality.

Net neutrality is the principle that consumers are not restricted in the ways they're able to use their internet connection. The topic is often in the headlines, either because some governments may want to prevent their citizens from viewing certain types of information - or because of commercial restrictions.

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.
