All you need to do is:
Log into iCloud.com using your Apple ID.
Click ‘Find my iPhone’.
Select your device from the ‘All Devices’ drop-down menu.
Click ‘Remove from Account’.
Click ‘Remove’ on the confirmation message.
If you've already put an Apple device in the Pod, or if doesn't switch on, you can still remove your iCloud remotely.
