I don't remember installing iToner ever. I own WireTap Studio though, maybe this was thrown in on that install but I don't remember WireTap Studio asking if iToner should be installed either.
Anyway, downloaded iToner from
http://www.ambrosiasw.com/utilities/itoner/. Installed, launched iToner and then iTunes 9.2 was able to sync. Next, threw iToner and all the supporting files, plist, plugin, etc. into the trash.
