The phone cannot be restored and unlocked via iTunes whilst this security feature is turned on. It is important that anyone wishing to unlock or buy an iPhone checks to see if this feature is turned on or not. If it is turned on you will need to know the iCloud password to turn it off or the phone may be totally useless to you.
