I used n900 and N9. It was posible to sync contacts todo's and calendars with own funambol server over syncevolution.
It was great!

Currently I use an android device and there is no way to sync todos is not posible because there are no standard api to do this. The lot of todo apps don't support funambol (only google) but I found the way to sync contacts and addressbook with funambol.

My question is Jolla supports fully SyncML for calendar, address book and todos? I must get sure before I buy this device.

On my Linux PC I use Akonadi with Kontakt and use syncevolution to push two-way sync to my funambol server.

Thanks for the answers.
