i had the same problem, when i connect my iphone (iso6) the contacts from my mac did not appear on my iphone, and yes under the info section on itunes the contacts was empty.
the only was i could sync my contacts was via icloud.
after calling apple care and going through several options, the last option was to reset the sync which fixed everything.
contacts from my mac address book sync with my iphone but the contacts do not appear in the info section in itunes.
