The Activation Lock web tool allowed users to enter a serial number of an iOS device to verify if Activation Lock has been enabled on it. Apple provided no explanation for the removal, but all checks point to it being a precautionary measure meant to prevent hacks relying on stolen serial numbers, as a reader pointed out in comments. The theft-deterrent tool allowed legitimate iOS device owners and just about anyone else to check the status of the Activation Lock feature by entering a serial number.
As we reported, Apple recently took down its tremendously useful Activation Lock webpage for reasons unknown.
