James Rosewell and Mark Bridge look back at the final day of Mobile World Congress 2012 in Barcelona. In today's programme they discuss Thursday's WIP developer conference, Visa's mobile payment plans and new services from Dolby.

Following Orange’s announcement that it’ll have an Intel chip in its own-brand smartphone later this year, Intel has revealed new partnerships with the ZTE and Lava mobile phone businesses.

It already has smartphone agreements with Motorola Mobility and Lenovo.

Ofcom is calling on the UK mobile industry to address the problem of consumers receiving unexpectedly high bills. It follows recent research that suggested 1.4 million mobile phone ‘contract’ customers may have been affected by ‘bill shock’ in the past six months.

The regulator says it may introduce new rules if mobile networks don’t tackle the problem.

Dolby is demonstrating HDR (High Dynamic Range) photo encoding on a smartphone at Mobile World Congress this week.

The technology combines a number of photos with different exposures to produce a final image that captures shadows and highlights without over-exposure or under-exposure. Each photo is saved as an JPEG-HDR file, which enables it to be viewed on conventional photo viewers. However, the additional HDR information remains in the image file, offering the opportunity of returning to the image after it was taken and using HDR software to adjust the exposure.

Wireless service provider UK Broadband has switched on its 4G LTE system covering the Southbank and Borough areas of Southwark in London.

Not only is it the first TD-LTE 3.5GHz deployment in the world, it’s also the first commercial 4G deployment in the UK.
