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.

Predicting the future is easy. Making accurate predictions is more of a challenge. In our final podcast of 2012 we've provided a forecast for the mobile telecoms industry in 2013 - and we've also looked back at last year's expectations.

So... what do the three of us at TheFonecast.com expect from mobile phones and wireless technology next year?

In this week's podcast we find BlackBerry facing a legal battle, SMS spammers suffering a big fine and EE boosting its 4G data tariffs.

We're also talking about a new iPhone camera accessory from musician will.i.am, rich cross-network communications in Spain, free WiFi in Yorkshire and the year's most-popular mobile search terms.
