Is it Facebook, ICloud, Yahoo, Google,LinkedIn, Itunes???!!!! I have over 1500 contacts and every time I edit contacts or delete them they soon reappear. I can't figure out where the mysterious syncing is happening. I only have 125 contacts in the cloud I just discovered. I see contact information that could only have come from Facebook or LinkedIn perhaps like job titles and companies. I've dinked around all my settings...I haven't a clue where to begin with how to resolve this...it is driving me nuts. I've tried apps like Simple Merge, Simpler, etc. to no avail!
