Is there really no unique id for calendar events retrieved through JSR-75 PIM API on Nokia devices? I am reading "Introduction_To_The_PIM_API_v1_1_en.pdf", and to my surprise Event.UID does not seem to be a supported field. I am working on a synchronization application and I need to be able to correlate PIM events with external events. For a meeting on a Series 40 device, stored fields are SUMMARY, LOCATION, START, END and ALARM. A user could potentially change all of these, how will I recognize this as the same event if UID is not supported?
