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.

Mobile networks aren’t what they used to be. As last week’s interview with Vince Russell of The Cloud demonstrated, more and more customers are relying on WiFi to augment their mobile data service.

Truphone is now planning to do exactly the same with voice calls and text messages by linking its mobile network with WiFi for even wider coverage.

Voice over IP service Skype has announced the first countries where customers will be able to use its direct mobile operator billing option. This will let customers pay for Skype credit by charging it to their mobile phone account.

The facility has just been launched in Russia and will soon be enabled in the USA and Canada as well.

We’re moving into that time of year where product announcements are replaced by promotional campaigns and sales figures. Apple revealed it had sold three million assorted iPad tablets in just three days, while Samsung said its Galaxy SIII smartphone had sold more than 30 million units since its launch in May.
