Iain, James and Mark look at the week's mobile news headlines, from Ofcom cutting termination rates to Opera launching its own application store... and they also hear how an unusual ringtone resulted in a criminal gang being apprehended.

O2 Media - the mobile advertising part of O2 - says its O2 More 'personalised media service' now has two million customers. It launched less than 1½ years ago in late 2009.

The O2 More service combines O2's own customer data with additional information provided by participating consumers. As a result, O2 More can offer personalised and even location-based advertising campaigns to its partners.

Ofcom has announced a reduction in mobile termination rates that'll be effective from next month. Mobile termination rates are the wholesale charges paid by mobile operators when connecting calls to their rivals.

The last time it set MTRs was 2007, when it agreed a series of charges that dropped annually until 2011.

BSkyB, BT, O2, TalkTalk, Three, Virgin Media and Vodafone have all committed to providing better and more easily comparable information to consumers about traffic management. It's a voluntary agreement that's been arranged by the Broadband Stakeholder Group.

The participating companies account for around 90% of all fixed-line broadband customers and 60% of all mobile broadband customers in the UK.

Sadly we’re ending the week with yet another natural disaster. Barely two weeks after New Zealand’s earthquake comes news of Japan’s biggest quake in living memory.

Still, I’m here to talk about mobile phones, so – after a quick mention of the great work being done by the Red Cross – I’ll get on with it.
