Hello I got a new phone today and when I downloaded the Facebook app and tried to log in a pop up came up and said application unavailable, the application you are trying to use is either no longer available or access is restricted. I've checked in the settings of my phone and there aren't any restrictions set for any thing, like I said, I just got the phone today. I've tried to install and reinstall with no success. Anyone have any ideas to what's going on?
There is a link like "forget password" Click that link. Some verification may required like your email account and sometimes facebook require friends verification. Hopefully your account will be recovered.
