With the disaster of the App Store I can't get wireless syncing to work anymore.  I do have a iPod Touch but when I open iTunes it does not connect to my iPod Touch.  I use to fix this buy opening up Process Explorer and terminating distnoted and SyncServer and then reopen iTunes but then it still refused to sync.  Then I usually fix it buy connecting the cable to sync it.  Then I disconnected the cable, closed iTunes and it still would not sync.  I gave up.
