Fix for iPod touch January Upgrade Sync Problem?

iPhone Atlas says that this Apple support article (Restore error messages on the iPhone and iPod touch) resolves the iPod touch sync problem that I ran into (see this O'Reilly Mac Center blog item). I'm not keep on wiping the touch (part of the instructions is NOT to restore from backup) and then manually resyncing and setting up WiFi again (a slow process) though. Will think about this for a while
