How can i split up icloud account. its the same for my wife and i but i would like 2 separate accounts. we both have iphone 4

Question

my wife and i both have iphone 4. they were set up with 1 icloud account. we now both have separate apple id's. I would like to set up a different icloud account on my phone with my apple id and password separate from my wife.

Answer 1

Decide which iPhone will be keeping the current iCloud account.  On the one that will be changing accounts, if you have any photos in photo stream that are not in your camera roll or backed up somewhere else save these to your camera roll by opening the photo stream album in the thumbnail view, tapping Edit, then tap all the photos you want to save, tap Share and tap Save to Camera Roll.  If you are syncing Notes with iCloud, you'll also have to email your notes to yourself so they can be recreated in the new account as they cannot be migrated.
Once this is done, go to Settings>iCloud, scroll to the bottom and tap Delete Account.  (This will only delete the account from this phone, not from iCloud.  The phone that will be keeping the account will not be effected by this.)  When prompted about what to do with the iCloud data, be sure to select Keep On My iPhone.  Next, set up a new iCloud account using a different Apple ID (if you don't have one, tap Get a Free Apple ID at the bottom).  Then turn iCloud data syncing for contacts, etc. back to On, and when prompted about merging with iCloud, choose Merge.  This will upload the data to the new account.
Finally, to un-merge the data you will then have to go to icloud.com on your computer and sign into each iCloud account separately and manually delete the data you don't want (such as deleting your wife's data from your account, and vice versa).
