Researchers in the USA have shown that it’s possible to identify friendships by looking at mobile phone call records and the proximity of users. They gave 94 people modified Nokia 6600 handsets that tracked communication, users’ locations and their proximity to other users.
The results from this five-year study, which have been published in Proceedings of the National Academy of Sciences, showed that the data could be used with 95% accuracy to predict whether two people were friends. In addition, the phone mobile data could also indicate the volunteers' satisfaction at work: those who said they were less satisfied with their jobs were less likely to have friends nearby and more likely to call their friends during work hours.

Marketing, not unlike football, is a funny old game. I don’t claim to be an expert in either… but every so often something happens that starts sowing the seeds of doubt in my mind. And no, I’m not thinking about Liverpool's penalty claims in Sunday’s game at Tottenham. I’m thinking about Blyk.
Here at The Fonecast, we like Blyk. They shook up the industry and worried some of the big names when they arrived with their youth-focussed virtual mobile network two years ago. We interviewed their MD Shaun Gregory in May last year. And now they’re quitting the MVNO game in favour of arranging advertising deals for networks.
