The iPhone’s locking and unlocking sounds have received minor revisions over the years, but perhaps not as many as we’d like. Fortunately, those with jailbroken handsets can get around this quandary by setting custom locking and unlocking sounds without Apple’s approval.
A newly-released jailbreak tweak called SoundLock by iOS developer DevelopApple is now available for free in the BigBoss repository, and it lets you configure custom sounds for a variety of locking and unlocking-centric actions that you might perform daily on your pwned iPhone or iPad.
