iCloud 활성화 잠금 완벽 해설: Clean vs Lost 모드 차이와 중고 구매 위험

iCloud Activation Lock is a cryptographic security protocol that permanently pairs an Apple device hardware identifier (UDID and serial number) with an owner's Apple ID on Apple central activation servers (albert.apple.com).

Neither status can be permanently bypassed without original owner credentials or verified authorized invoice documentation.
