How can I sync only the Facebook contacts which already exists in my phone memory? I don't want to sync the contacts that are not on my phone memory.
You could choose to only show contacts that have phone numbers. If I remember correctly, this is in Contacts -> Menu -> Display options -> Only contacts with phones.
Another possible solution is to go to Settings -> Accounts & sync and remove the Facebook sync, Add account -> Facebook and in this process select Sync existing contacts only.
I'm not 100% sure about the menu item names, but they should be somewhat similar. It's been a while since I've used Froyo.
Facebookshows up underAccounts & Syncwill depend on your ROM and what apps it comes with or you have installed. – eidylon Feb 02 '12 at 16:30
