This week there was only one set of financial results that attracted the mainstream tech media. Apple reported the first drop in quarterly profit for several years as figures fell by 18% to around £6.1 billion. On the positive side, it made around £6.1 billion profit. It also announced dates for its developer conference in June and promised a new version of iOS.

There's a diverse collection of mobile-related news in this week's 30-minute podcast.

We start with the new Twitter music service before moving on to discuss quarterly results, patent licensing, wireless charging, advertising and mobile payments... before ending with a curious report about app-controlled underwear.

The last of the 2012 quarterly results are coming in, so it's time to compare figures from the biggest mobile handset manufacturers.

We're also looking at Twitter's new video app, discussing the forthcoming Firefox OS and preparing for the BlackBerry 10 launch later today.

I didn’t study economics at college, which is probably one of the reasons I have a very simple perspective on quarterly results. As far as I’m concerned, they fall into one of three categories: much as expected, better than expected or worse than expected. Anyway, it’s the time of year when some of the biggest names in the mobile telecoms industry publish their financial results – so here we go.

It's another packed podcast this week, starting with mobile payments and ending with DIY mobile accessories.

We also cover manufacturing news, mobile VoIP calling, a new virtual network heading for the UK high street, shop closures, smart accessories and phablets.
