Need help with removing iCloud from your device? You're in the right place.
iCloud is Apple's cloud storage service that stores data and pushes it all of your Apple devices.
In iOS7, Apple introduced Activation Lock, which prevents your phone from being activated without the password of the iCloud account on the device.
We are unable to accept any devices that still have an iCloud account on them or are activation locked.
There are two ways to do this: from the device itself, or from iCloud.com.
From the device:
Step 1: Go into Settings.
Step 2: Select iCloud.
Step 3: Tap to turn off Find My iPhone (or Find My Device)
From iCloud.com:
Step 1: Turn off the device.
Step 2: Log into icloud.com with your Apple ID and password.
Step 3: Select Find My iPhone.
Step 4: Click on All Devices, and choose the device that you're sending in.
Step 5: Select Remove From Account.
If you've sent in your phone already and you need to follow the iCloud.com instructions, your phone will already have been turned off.
