O2 says its 4G network now reaches 41% of the UK population outdoors and a third of the population indoors.

Currently 191 towns and cities have O2 4G coverage.

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.

Telefónica, the company behind O2 UK, has announced a new organisational structure and a new strategy.

The new structure is intended to be simpler and ‘completely focused on clients’. A new role of Chief Commercial Digital Officer has been created and the activities of Telefónica Digital, Telefónica Europe and Telefónica Latam are being moved into the main business.

This podcast takes a look at the issue of finance for start-ups - and, in particular, at Accelerators for tech-based companies.

It's a discussion that was recorded at Mobile Monday London earlier this week with a panel including Jon Bradford of Techstars, Simon Devonshire from Telefonica's Wayra, Diane Perlman from Microsoft Ventures and Simon Cook of DFJ Esprit.

Iain Graham, James Rosewell and Mark Bridge return with their first mobile industry podcast of 2014.

This week they're looking at new Samsung, Sony and ZTE products from CES, they're talking about Android embedded in cars, they're catching up with the latest news from BlackBerry, they're discussing cheque payments by smartphone, they're revealing complaint data from Ofcom and they're investigating quite a few other stories as well.
