Sync eGroupware with Sony Ericsson Phones

Current Sony Ericsson cell phones feature a SyncML client that allows synchronization with eGroupware. In Organizer -> Synchronization, create a new SyncML account, provide a name, 'https://groupware.phys.ethz.ch/rpc.php as Server Address, and your D-PHYS credentials. Then save the account data and edit it to select the data sources you'd like to sync. Find the necessary information on https://groupware.phys.ethz.ch/syncml/index.php. The first (few) sync runs seem to fail, but afterwards it works fine.
