Back in December, Three UK had an advertisement banned by the Advertising Standards Authority because it hadn’t explained the possibility of monthly charges rising during a fixed-term mobile phone contract - and now Vodafone’s web site has been hit in the same way.

A tariff promoted as costing “from just £10.50 a month” caused a complaint from a member of the public who pointed out that the monthly price could be increased during the contract.

Facebook has reported its fourth quarter and full-year financial results for 2012, with quarterly revenue up 40% year-on-year to $1.585 billion but net income down over 78% to $64 million.

However, the social networking company noted that its research & development costs had more than doubled from Q4 2011.

Staff at major UK retail shops are more likely to recommend a Samsung smartphone or tablet than an Apple device, according to a small survey carried out in London by Informa Telecoms & Media.

A mystery shopper who visited eight shops on Oxford Street in London found that Apple and Samsung were the most promoted brands while Huawei, LG, Motorola, RIM and ZTE had little high-street presence.

Targeted advertising on mobile devices is something we’re all getting increasingly familiar with. Visit a web site and there’s a good chance you’ll see an advertisement that’s aimed directly at you, perhaps using information about the sites you’ve previously visited, the type of smartphone you’re using or even your location.

Yet listen to the radio or stream music on your smartphone and that same level of personalisation hasn’t been aavailable. That’s all changing now, with help from a new service called UTuneMe.

In this special feature we're talking to Shankar Meembat, co-founder and CEO of Exaget, about the company's new UTuneMe service.

It lets broadcasters add targeted audio advertisements to radio programmes that are streamed onto smartphones.
