A new tweak has released naming as CallLock.CallLock is a tweak that locks your iPhone screen during a call. It can be enabled either manually or automatically and will prevent you from accidentally pressing buttons that could dial, mute, hold, or hangup a call by mistake. This is especially useful for people who have a faulty proximity sensor in their iPhone 4.
CallLock will override the default action of the Power button during a call to lock the screen instead of the normal end call action.
CallLock will automatically lock your screen as soon as a incoming or outgoing call is connected.
To enjoy this tweak, your device must be jailbroken on iOS 4.x.You can download CallLock for $0.99 from the Cydia Store via BigBoss repository.
