'UnlockSound7' Brings the Lock Screen Unlock Sound Back to iOS 7
Shh... what's that noise? *crickets*
The iOS 7 lock screen is a lot quieter than it used to be in previous versions of iOS. Apple appears to have done away with unlock sounds that play when you unlock your iOS device, although for some reason, they kept the lock sound that plays when you lock your device.
If you want to bring the unlock sound back to the iOS 7 lock screen, you will find a new free jailbreak tweak in Cydia called UnlockSound7
by iOS developer merdok.
After you install the tweak, and you have "Lock Sounds" enabled in your Sounds settings, you will hear the unlock sound that we have all heard before on previous versions of iOS when you go to unlock your device via the lock screen.
UnlockSound7 also adds a preferences pane to the Settings application where you can configure a few additional options:
Here, you will be able to enable or disable the tweak on demand. You'll also find a way to either use the classic iOS unlock sound, or use a custom sound of your choice. If you want to use a custom sound, you'll have to have a short .caf file named "unlock.caf", and you'll need to place it under /var/mobile/unlock.caf.
You'll also find yourself with a custom volume slider, which will allow you to override the device's volume level for a custom unlock sound volume. You can enable or disable the custom volume, depending on how you're feeling about using it.
UnlockSound7 is a great way to bring back some life to the iOS 7 lock screen, and it's even cooler that it lets you have a custom unlock sound at that. Not to mention, you can't beat the free price tag. If you want to give the tweak a try, it's available for free in Cydia's BigBoss repository.
