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.

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.

BlackBerry and bad news seem inextricably linked at the moment. RIM’s CEO admits he’s “not satisfied” with recent company performance and warns of challenging times ahead... and then the company is hit by a $147 million dollar damages order for patent infringement.

Mind you, Research In Motion wasn’t the only mobile company bringing disappointment into the mainstream news last week.

This week's edition of The Fonecast takes a look at the new Google Nexus 7 tablet, wonders what's next for RIM and awaits the arrival of the forthcoming Firefox mobile platform.

There's also talk about HTC's partnership with Pioneer, Vodafone's European reorganisation, the new BT WiFi brand, Ofcom complaints, tariff problems and international roaming.

Here in the UK, we have a double Bank Holiday weekend to celebrate the Queen’s Diamond Jubilee. That means two days away from work for many of us (and also two days of unseasonably bad weather, according to tradition).

In fact, the three of us at The Fonecast are celebrating our own anniversary this month. It’s been six years since we started podcasting about the mobile phone industry. We’ll be revisiting some of those early programmes - and the biggest mobile news headlines from 2006 - in this week’s podcast on Wednesday.
