Fill your boots, Facebook
If you supplied your phone number, or any other personal details about you and your friends, you shouldn't be at all surprises that it is on Facebook
BUT.....
A lot of people didn't know this list existed until now.
The settings are quite well hidden unless you are specifically looking for it.
In my case the settings on my phone are switched off, to NOT sync yet the numbers still got harvested.
The numbers are not just my own or the numbers of friends on Facebook that have already supplied - there are numbers from contacts in my phone that are not even on Facebook and have no business being on there.
By all means allow information to be copied across ... But tell your users you are doing it first. Better still, ask for their permission
