I'm working in iPhone repairing and programing I have daily customers which icloud is activated so if anyone can help me to clean icloud I'll pay and make business with him
It's not possible to bypass iCloud activation, if that's the problem you're facing.
In case you're trying to remove the iCloud ID from an iDevice without the owner's knowledge: that's illegal, thus piracy. We don't discuss topics like these on iPhoneForums.
