A new research study conducted by Kantar Media on behalf of UK telecoms regulator Ofcom has shown that mobile application users believe apps are safer than accessing the internet via a browser.

These consumers also trusted well-known app brands and official app stores to provide a safe, secure and reliable user experience.

Even at Mobile World Congress, the relevance of the mobile network operator can sometimes be forgotten. So for a different perspective on this year's event, we spoke to Samuel Johnston from British mobile crowd-sourcing firm OpenSignal.

Samuel discussed the announcements from MWC14 and OpenSignal's latest report into 4G LTE coverage around the world, as well as giving us an exclusive insight into OpenSignal's next research subject.

This week's programme begins with some of the biggest news stories that came out of Mobile World Congress.

Iain, James and Mark then move on to the other headlines from the past few days, including Boeing's secret agent smartphone, Apple's plans for mobile in-car entertainment, a new structure for Telefonica and new technology for mobile payments.

Peter Oppenheimer, Apple’s senior vice president and Chief Financial Officer, says he will retire at the end of September this year.

He’ll be replaced by Luca Maestri, who’s currently vice president of Finance and corporate controller at Apple.

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.
