How to disable SMS preview displayed over a locked screen? On an Android device (HTC Desire S if that matters) with a locked screen whenever an SMS is received it's preview is displayed over the locked screen. This is super inconvenient - anyone who is nearby can see it without even unlocking the screen.

Is there a way to disable those previews over a locked screen?
You can do so by going into the Messaging app, and pressing Menu -> Settings -> Uncheck "Received notification (Show  notification in status bar when messages are received)". 

But you won't get the notification on status bar as said above.
