Here we are in 2010 and still no means of moving a calendar entry from one calendar to another. Can't be done in the calendar app, can't be done via the mobile version of the web-based calendar, and the desktop version of the web-based calendar can do it but it won't work in the android browser so if I need to move entries between calendars (which I do need to do regularly) I need to find a desktop computer
Does anyone know of a third-party calendar app that permits events to be moved from one calendar to another?
