I was trying to import contacts to promote my facebook page. I entered my gmail address and I got message saying
We can’t import contacts from this address yet.
You may try one of our supported email addresses.
I know that in past Facebook used to support GMail as well. But recently they might have done some change to stop supporting GMail.
I think this is the direct indication that Facebook really want users to use Facebook Mail instead of sticking to GMail.
WAR IS ON!!!!!!!!!
