How To Recover deleted messages from Blackberry

We sometimes find ourselves doing things automatically only to find out later that what we have done is a mistake!  At the very least, this is an inconvenience.  This could apply to almost anything, especially when a person is multi-tasking.  An instance where this could happen is when you?re talking to someone while checking your Blackberry for messages.  If you?re deleting a previous message, you could accidentally do the same to a new one thinking that it is old.  It wouldn?t matter if the email or text is unimportant.  But what if it is a message from your boss or business associate?  What will you do?  Can you recover the message from somewhere just like in Yahoo or Google mail?
