iCloud Contact "(null)"
Since a Genius bar guy transferred my iPhone content to another handset, my Contacts on my MacBook Air keeps adding "(null)" to my iCloud Contacts list. Why and what can I do to stop this ?
Also, my Contacts are i) split between between All iCloud and on My Mac, ii) don't synchronise between the two groupings despite having the same groups, and iii) my Mac don't sync with my iPhone either.
