Most of my contacts that I'm also connected with on Facebook, no longer have any email address in Contacts. Sigh!
The problem is described here:
I have a backup in iTunes, but I dunno if it's after the incident occurred. Then I would have to merge it into Contacts, but it seems like a tricky operation.
I can also go through all my sent/received emails in gmail and copy/paste the addresses from there into Contacts, but it seems very time consuming and may not be a full restoration.
If I restore the addresses, will Facebook then delete addresses again. Should I wait restoring until there is a new Facebook app where the problem has been fixed?
How to restore the deleted email addresses?
