Phone books maybe a bit out dated these days as no really uses them so much. So now, this new idea of having a phone book with mobile numbers does sound like something strange. A UK firm called Connectivity is launching a directory service for people’s mobile numbers. A complete directory of mobile users, which you’ll be able to ring up and pay to be put through to someone. But the million dollar question is that who will agree to this kind of service as people tend to be too possessive about their mobile numbers. Wonder if it will work?
