can i lock contacts only

[Guest aawong]

I am looking to lock only the contact or address section of the phone? Can this be done on a 5600 or can it be done with added software?

That way if my girlfriend needs to use the phone to make a call or listen to mp3's she can and i don't have to worrie about her geting a hold of my other girls contact.
