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.
