ADO.NET driver - non Beta version

Hi folks,

We currently have BETA ADO.NET driver and I recently read John Appleby saying that there is now support in SPS08.  Currently we have a mixed environment, doing most of our development on rev 68 while our 72 server sits waiting to apply SPS08 any day now (due to several issues we had with 72 we abandoned it).  My question is how can we get our hands on a NON-BETA version of ado.net driver?  Can somebody point me in the right direction?

Thanks
