Need to back up my husbands phone and save contacts.
Need to back up my husbands phone as he is getting a new one. I have backed up his existing phone to my iTunes. Tried to sync contacts but a message says 'synced to another account'. He can't remember the account. Should I merge contacts to my iTunes? Will this put all of his contacts onto my phone?
iPhone 5, OS X Yosemite (10.10.5)
