Tweak that deletes messages (and other stuff) permanently?

[iMore Question]

Hey everyone,
Was wondering, is there a tweak in cydia that deletes messages permanently to the point where they cant be recovered? Sort of like the WonderShare safe eraser desktop application? It would really help if someone could chime in. Thanks in advance!
