Have you found after a while you’re sick of iCloud and want to get rid of it? Or maybe you just want to start all over again with a new account?
You can actually delete your iCloud profile directly from your iPhone.
To do so, head to the Settings app, and then click on “iCloud” under the “General” option. Down the bottom, under the “storage and backup” option, you can click the red “delete account” option.
The phone will ask you if you’re sure – think about it, then answer.
