Great news for everyone waiting to see what will happen with the Like refresh issue on the new Timeline for Pages. Facebook confirmed today that this is a bug and the fix will be in place soon.
This Like refresh issue prevents the page from refreshing when the Like button is clicked on the new wide format page tabs. If you rely on that refresh to show different content to users after they like your page, the user currently has to refresh the page on their own making for a poor user experience. If you’ve already upgraded to Timeline and have live fangate campaigns, it shouldn’t be long before they are working as you expect.

Update 3/7/2012: Facebook implemented changes today to fix this issue.
