How can I trick SBS 2011 into allowing me to assign a UPN alias so users can logon as [email protected]
See http://support.microsoft.com/kb/243629/en-us
But on SBS I only have a 'General', 'Trusts', and 'Managed by' tab.. this is SBS 2011.

You're looking at the wrong set of properties. In ADD&T right click the "root" object, not the "domain" object, select properties, and add the UPN suffix.
