The above is KLM's policy. No phones, smartphones etc may be used on board when in flight, whether in flight mode or not. It's one of the reasons why I never bought an integrated device.
Would be interested to see what they'd say about an iPod Touch, though, as this is basically identical to an iPhone except for that it doesn't have the phone component.
