Just upgraded from the 4 to the 6plus and gave the 4 to a friend. She says she cannot activate it until I delete the device from my iCloud!? I have no clue how to do that? Help!
On a browser, go to www.icloud.com
Login with your AppleID and password
Go to settings
Click on the device you want to remove
Click on the Red text Remove Device
Or on the device it must be connected to wifi and then go to settings then iCloud and turn off find my iPhone. the the phone can be reset and activated by someone else.
