I'm afraid I cannot do anything about it; you'll have to contact Funambol. As a workaround you could try setting up a SyncEvolution configuration manually as explained on estamos' Installation page.

I'm entering my username and passord into the settings, and when I close it reverts back to the guest account... any idea? I’ve just upgraded to 1.1.3 and the SyncEvolution plugin doesn’t work!

It hasn't been needed since Mark changed the ScheduleWorld DNS setup anyway. On my iPhone (1..02 firmware) the entry survived reboots and I had completely forgotten about it when syncing failed with "Error in preparing sync: libcurl error 7, couldn't connect to host"...

If possible I'd like to avoid messing with that file in SyncEvolution code. Perhaps an iPhone startup script can be written which adds user-configurable entries to /etc/hosts on each boot. I had started to investigate this issuse by taking network dumps of the name server lookup, but the results were inconclusive. I suppose I need to continue this work to really identify the relevant difference between my.funambol.com (which always seems to work) and sync.scheduleworld.com. I'm traveling right now and won't have time before next week, though. There's one more thing that could be tested (but I doubt that it'll work): setting the fixed IP address in the syncevolution config instead of sync.funambol.com. The reason why I expect this to fail is that the server's response will probably redirect the client to the normal name. It is worth a test, though. Anyone willing to try it and prove me wrong? ;-) The configured IP address still needs to be in /etc/hosts because libCURL (although inside the syncevolution binary) will always read it from there or DNS.

I'm aware that IP can be changed of course. Then one will have to reflect this change in config. It is not nice, but better than nothing.

I had not yet rebooted, so I wasn't aware of the fact that the setting gets lost - bummer. I suppose syncevolution could add the setting, but which one? The IP address might change and I don't want to update the binary just because of that. It just doesn't smell right.

However the content of /etc/hosts does not survive reboots. Any suggestions? Ok, may syncevolution application add the needed record into /etc/hosts on the start?
