I understand Using one iTunes ID for purhcases and the Apple @me accounts for the cloud. My mother is getting and iPhone and we are a one Laptop home. I don't want anything of her phone getting on mine or anything on mine getting on hers. Is this possible using the iCloud, if we each have our own @me accouts?
The iCloud just seems too open. I don't want any app or message or contact cossover. Can someone please tell me if this is possible?
iCloud separates all your stuff from someone else's. This should be an individualized Apple ID (separate from any other family members). When setting up a new iOS device, you'll have the option to create an @me.com address. This will serve as your individual Apple ID.
This individual Apple ID (iCloud account) includes: Contacts, Calendars, email, reminders, bookmarks, photo stream, documents & data, and Find my iPhone.
On all apple devices, you have an iCloud setting. Turning this on will allow you to associate your iCloud account (your new @me.com address) so all your iCloud devices (iPad, Macs, etc.) will sync across all your other Apple devices associated with that same iCloud account. In other words, if I update a contact...all my Apple products with iCloud enabled & associated with my personal Apple ID iCloud address will update immediately.
IN ADDITION, under Settings > Store, you can associate a completely different Apple ID to purchase content. Everyone you want to share your purchased content (music, apps, movies, books, etc.) will use this same Apple ID under Settings > Store.
Again, you can tell you iPhone in Settings > Store to use one Apple ID, while in Settings > iCloud you're telling it to use a completely different Apple ID.
Now to throw more fuel on the fire, you also can associate an Apple ID to Settings > FaceTime and Settings > iMessage.
In my family of 4, we all use the same Apple ID for purchased content. However, we all use our personal Apple ID (@me.com) for iCloud, FaceTime, and iMessage.
Using this method, all purchased stuff can be shared in the family; however, all personal stuff (contacts, calendars, etc.) remain private.
