SyncEvolution-GUI is a very basic Graphical User Interface for the N9. It is basically only a GUI for the syncevolution command line tool.
There is currently no configuration options available. All settings have still to be done in the config files as described here, http://forum.meego.com/showthread.php?p=35414 or http://talk.maemo.org/showthread.php?t=85868.
syncevolution 1.3 can be downloaded here: http://people.debian.org/~ovek/harmattan/
