i have a problem that i dont think anyone can resolve. i have modded some of the sound files , i have managed to get the numbers on dial pad to speak the number , and email, text, and voicemail changed but for some reason the lock & unlock sounds have vanished. nothing nada, there is no sound when unlocking or locking , have downloaded copy of orig unlock and it plays in quicktime but when placed in folder via ssh nothing works, have resprung and powered off and restarted to no avail.

any suggestions appreciated
