While syncing I wanted to stop getting the email addresses so I clicked that off. No reason to think the phone numbers wold be affected, it did a backup of iphone before proceeding. After the sync – poof – all but maybe 3 phone numbers were gone – no idea why they remained. So I clicked back the email addresses and tried another sync. Yep – those phone numbers are GONE. So is there a hidden file I can check on, something like a dated and time stamped backup like windows restore? Sure would like to get those numbers back ! Makes this itunes thing a real piece of work compared to just seeing it as another drive! Thanks for any ideas – other than an email to the folks to get their numbers back.
