I noticed a new phenomenon at Mobile World Congress this year: Beer O’Clock. Come 5pm Monday through Wednesday, companies with larger booths would break out the Cerveza, Vino, Cava and a small number of Orange juices. All very sociable and fun… until the music started.

The new Apple iPad tablets, Google's latest Nexus devices, Android Lollipop, wearable tech from will.i.am and the world's slimmest smartphone all feature in this week's podcast.

We're also talking about free mobile data for Christmas, 4.5G technology being rolled out in the UK, 5G technology being tested in South Korea, the end of an era for webOS and video messages that self-destruct.

There are many mobile boundaries being blurred in this week's podcast.

Topics include Truphone's combined WiFi and mobile service, Skype's move to direct mobile billing, the rise of 4G and an Android-controlled satellite.

Ofcom, the UK government and the major networks have all agreed a timetable for 4G to be launched across the UK.

We're talking about those plans in this week's podcast - and taking a look at all the other top mobile industry stories as well, from US mergers and leaky tablets to free WiFi and forthcoming quarterly results.

Nokia reveals its first two Windows Phone 8 smartphones in this week's podcast, while Amazon announces a handful of new tablets.

And if that wasn't enough, there's an update from Everything Everywhere about its plans for 4G in the UK.

We talk to two very different companies at Mobile World Congress about their businesses and their relationships with mobile networks. Rebtel is a mobile voice-over-IP provider, while Mosaik Solutions produces mobile network coverage information.
