How to Remove Apple iCloud:

  1. Open the Settings app and go to “iCloud”
  2. Scroll down under all the settings to find “Delete Account” (or “Sign Out”) and tap on that
  3. Confirm the removal of the iCloud account from the device by tapping on “Delete” or “Sign Out”

Note that the newest version of iOS uses “Sign Out” in the iCloud settings panel, whereas the immediately prior versions use “Delete Account” – the effect is identical, it’s just a change of wording. Both will log out of the iCloud ID account on the iPhone or iPad.
