Yes you can, it has that option that it does not touch the photo in phonebook if you already have it. Or when results come, just unlink the profile with a name. App is almost perfect for this...only, it downloads very blurry photos to phonebook, Im guessing that the photo should be 2 mpix to look good. It will sync only photos of contacts which you have on your phone, it does not download names that arent on your phone.
