Go to your applications and press firmly on the Facebook application. It will now appear on the home screen you were on when you went into your applications.
I understand that process but it only brings in "social network" folder. Thanks anyway
After using Google and going through numerous pages I found out how to rectify this is issue if anybody else was having same issue....
Market Place > Search > type word "Facebook" > download it.
Droid X comes with something associated with Facebook, but isn't the same Facebook I had on my Blackberry. BUT going through market place and downloading it, it is now like my blackberry but 30x better!!!!
