The hardware in iDevices varies (obviously) between the many devices which have been produced over the years. But I believe that you're right in that it's not possible for the OS to tell when data has /really/ been written to permanent storage. Such writing takes a lot of power and it makes sense that a device would want to do it infrequently. Simon.
