Talking iPhone lock and unlock sounds for default locker

dont forget to back up your default if you want to go back..

first, get the zip here; dont worry its working on GB too..

put the zip file on your phone (or extract it first if you prefer)

open Root Explorer and mount RW(X-Plore file manager also works, you need to set it first to SU + mount RW mode)

rename to Lock.ogg and Unlock.ogg (i think the caps matters so its just for safety)

copy Lock.ogg and Unlock.ogg to system/media/audio/ui

overwrite all

set permissions to this
R W X
Owner V V
Group V
Others V

no need to reboot. enjoy!
