Your Mobile Phone Number is not Safe with your Mobile Operator

There has been a lot of fuss today about mobile network O2 handing out the mobile numbers of its customers to websites that they visit.

That's clearly an unfortunate occurrence, and O2 users as well as the web in general were understandably outraged. But what surprised me was not that it happened at all, it was the fact that the public really don't understand quite how widely it was happening already.
