I did check out majority of the plugins out there, but none seemed to work with 3.0.1. I did figure out the best solution though. To do this, you just need to add this to the .htaccess file:
RedirectMatch 301 /([0-9]+)/([0-9]+)/([0-9]+)/(.*)$ http://www.domainname.com/$4
Just place domainname.com with your domain. I put it in write after the ReWriteBase / command.
