I have a Droid 2 and I just called Motorola. She did not have an answer on how to unsync Facebook contacts, but she did suggest changing the contact display options, and that worked. Go to "Contacts". Press the menu button. Select "Display Options" Scroll to "Choose contacts to display". All your current accounts should be listed here. Select "Facebook". Uncheck "All Contacts" Then touch "Save". Some one suggested going to something called "Accounts and Sync" but there is no such thing on my phone. Only a thing called "Accounts" under which the only menu option is "Add Account" No sync options anywhere.
