In our podcast this week we're discussing the new SmartWatch from Sony, talking about Firefox OS smartphones and contemplating Vodafone's partnership with Sainsbury's.

We're also looking at complaint figures, roaming charges, pay as you go pricing, joint ventures, BlackBerry's recent results and the future of Windows Phone.

The European Union’s Roaming Regulations, which were put in place last May, have caused mobile roaming charges in Europe to fall again today. Charges fell last July and are scheduled to fall again next year.

Although maximum prices for voice calls and text messages are falling slightly, there’s also a dramatic drop in the maximum cost of mobile data usage.

We start this week's podcast with Apple's announcement about the new version of its iOS platform - and follow this with a look at the privacy concerns surrounding the US government's PRISM operation.

Next come Samsung's new phones, Ericsson's new contract, a potential end to European roaming charges, some sophisticated mobile malware and plenty of other news stories as well.

Neelie Kroes, Vice-President of the European Commission responsible for the Digital Agenda, has called on European MPs to end mobile roaming charges.

In a statement, she said “I want you to be able to go back to your constituents and say that you were able to end mobile roaming costs. I want you to be able to say that you saved their right to access the open internet, by guaranteeing net neutrality. I want you to be able to say we took real action on cybercrime and other threats.”

Mobile roaming, messaging and networking Syniverse is selling part of MACH to complete its takeover process.

Syniverse has been given the go-ahead to acquire its rival but the European Commission insisted that most of MACH’s data clearing and near real-time roaming data exchange business in the European Economic Area was sold to another buyer.
