I broke my 8900 yesterday and am borrowing my friends 8800/8820. How do you tell the difference? Anyways I couldnt get some messaging features to work and tried to delete some service books and undelete them. The problem is i deleted them all at once before trying the undelete not knowing the undelete only works on the previous delete. So now im stuck without any service books. Is there any way to restore them? Desktop Manager? Need help please.
