My wife and I have separate email addresses (AOL), but share our iCloud Contacts and Calendar info. She wants to have different music on her phone from me. How do I sync from the cloud with our phones?
See my post in this forum about sharing photostream.
You could do the same thing - setup a joint iCloud account wand share calendar and. Intact. Then use your own iCloud account by adding it in the mail accounts for private email.
