Every time I try to use the app with wifi sync enabled it complains about the desktop app being locked. Well, duh. You shouldnt leave 1P unlocked and unattended, so I dont see why the iPhone app is throwing tantrums. And its not like I need to sync passwords all day every day, no need to notify me with a modal alert window.
