How to obtain the phone number when reading facebook contacts

Question

I thought it was impossible to read phone numbers of contacts using facebook APIs, but "Facebook for HTC Sense" android application is syncing all that information to my local agenda.

Somebody knows how are they implementing this feature?

Answer 1

Is it for people you already have in your contacts? It's possible they are just cross-referencing other pieces of information (like email) against your local contact info.

Because phone number isn't a field in the graph nor is it one in the corresponding FQL table.
