I am developing an application in java for the nokia 9210 to update contacts and calendarentries. I want to do this via de UID field (because I think this is the field to use for finding uniquely the contact) but i get stuck. the iterator only seems to accept string values (while the value should be byte[]) but doesnt find the contact. Am I doing something wrong? I hope so. The CalendarDatabase doesnt support the UID field at all, isnt it?
