Question

I have changed my Apple ID but the account info on iCloud is still referencing the old ID. How do I change the iCloud account details?

Answer 1

If you simply renamed your ID, you can go to Settings>iCloud and tap Delete Account.  This will delete the account from your phone (but not from iCloud) as well as any synced data.  But provided you are signing back into the same account (just with a new name) it will be synced back to your device when you sign back in.  Then set up your iCloud account with the new ID name and turn syncing back on.  If you have photos in your photo stream album that are older than 30 days that you don't have anywhere else, you will need to save these to your camera roll before deleting the account. To do this, open your photo stream album on your iPhone in the thumbnail view, tap Edit, tap all the photos to select them, tap Share, then tap Save to Camera Roll.
If, however, you are changing to a new ID you'll have to delete the account, create a new account with the other ID, and migrate your data to the new account.  To do this, first go to Settings>iCloud on your phone and turn all data you are syncing with iCloud (contacts, calendars, etc.) to Off.  When prompted choose to keep the data on your iPhone.  After everything is turned off, scroll to the bottom and tap Delete Account.  (Be sure to save any photo stream photos to your camera roll prior to deleting the account, as mentioned above.)  Next, set up a new iCloud account using your new ID, then turn syncing for your data (contacts, etc.) back to On.  When prompted, choose Merge.  This will upload the data to your new account.
