Can you restrict the facebook integration to the iPhone contacts to just my iPhone contacts?

Before you do anything, you’ll need to turn off the auto-sync feature on your mobile phone. For an Android phone, go to Menu>Settings>Account and Sync>and uncheck the Auto-Sync box. For iPhones, open the Facebook application for your phone, then you’ll need to click on the “Friends” icon, and then click “Sync”.
Go to your Facebook homepage on your computer, and click on Account>Edit Friends>Contacts. You’ll see a full listing of all your phone’s contacts, mobile and home phone numbers included. On the right-hand side of this page, you’ll see a link to click on to get the process of removal started.
You’ll receive a message from Facebook informing you when the removal is complete. Once you have confirmation, go back and turn on your syncing again.
