I just bought an HTC One X and I'm having some trouble with syncing existing contacts with facebook. For some reason, adding the facebook account and selecting "Sync with Existing Contacts" would also unexpectedly add several unwanted contacts under the call list. The phone seems to automatically add non-existing contacts that have a phone number in their facebook profile.

How can this be solved? Any way to prevent these contacts from being listed? or perhaps any way to manually delete these contacts?

Thanks
