Yupp, still based on evolution-data-server, so updating syncevolution should be perfectly doable. Which is a nice solution for open syncml-solutions like Scheduleworld, but unfortunately not for "Contacts on OVI".
The syncml-server username+password for the later come as part of an SMS and are thus not visible to user. At least I have not found a way to read them out, but I do not know to much about S60.
