A new iOS and Android app called Sidecar promises to enhance mobile and WiFi voice calling with additional ‘smart calling’ features. Users can offer video, photo sharing and location information during a voice call.

An additional benefit is the ability to call any mobile telephone number in the US and Canada for free when using WiFi, even if the recipient isn’t using Sidecar.

Microsoft has released the ‘Gold Version’ of Skype for Windows Phone, marking the end of the product’s beta period.

The beta version was launched during Mobile World Congress in February.

VoIP and video calling service Skype is now available for Windows Phone devices.

A beta version of the WP7 app is available now, with the finished ‘gold’ version due in April.

ABI Research says mobile video usage is expected to grow dramatically during the next five years - but it won’t become the ‘new voice’.

Video telephony, video sharing and video messaging services over mobile networks were used by less than 47 million consumers at the end of last year. However, usage is expected to grow eight-fold to reach 390 million users in 2016.

Google has augmented its Google Talk instant messaging app to include video and voice chat for Android phones.

The new service enables consumers to make video calls over 3G or WiFi between phones or from a phone to a PC. Text chat from the person you're talking to will appear in front of the video on your phone's screen.

Mobile World Congress is just a week away, with lovers of mobile technology preparing to be wooed by manufacturers, networks and developers. But if MWC is like St Valentine’s Day, then LG has been behaving rather like the world’s worst boyfriend.

Mobile phones have been hitting the mainstream news over the past few days. There was Channel 4’s report about data on second-hand phones not being properly deleted before the handsets were re-sold, there was the latest round of the Smart UK Project and there was Tim Muffett’s story about the mobile-enabled high street on BBC Breakfast this morning.

Patents were a very popular topic of conversation last week. Google sold its Motorola Mobility smartphone business to Lenovo but hung on to most of the patents. Does this mean the patents were the most valuable part of the business? Well, when you look at the difference between the original purchase price and the sale price, it seems a reasonable conclusion.

Sometimes I worry that I’m turning into a grumpy old man. That I’ll follow the path of Rick Wakeman and become better known for my views on body piercing than for playing ‘The Six Wives of Henry VIII’ on eleven keyboards simultaneously.

There was great news for some BlackBerry owners this week. The new 10.2.1 update to the BlackBerry 10 OS was released, offering a new incoming call screen, SMS and email groups, more options for locking and unlocking, extra battery usage information, enterprise features and - for customers with a BlackBerry Z30, BlackBerry Q10 or BlackBerry Q5 smartphone - an FM radio.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
