All Day events created in iCal and then synched to a Sony Ericsson K610i, K790i, or K800i phone will appear to be marked as All Day Events, but this status may instead appear as the start / end time of the event. This occurs if the All Day Event is edited after synchronization.
Apple has identified this as limitation of the mobile phone device.
