The method above worked for me. I also removed Air Sharing, which has been reported as causing problems elsewhere. After completing the rest of the steps, I downloaded Air Sharing again and it continued to work.
One note: I had to delete the apps from iTunes, not simply uncheck them as some have reported as working elsewhere.
One odd thing, which is probably related but not a big deal: in the "Open in" dialog for a PDF in Mail, the iBooks logo is appearing on the Air Sharing button, and previously the Air Sharing logo was appearing on the iBooks button.
