I just discovered this and its working. Syncing should work via wifi connection.

-go to https://www.ovi.com

-select calendar or contacts

-then log in or create a new OVI acount

-on the lower left there should be an option to select your device "Manage your Device"

-input your phone model and just follow the instructions, Ovi should send you a SMS with settings for OVI syncing and dont forget to write down the 'PIN' that is written on the webpage.

-you should recieve a SMS from OVI with settings, input the pin code and save the settings

-now go to contacts>options>syncronization and select Ovi.com It should sync your contacts, calendar and notes. You can also go to Settings>Syncronization

-after syncing you can also edit and/or add new contacts/calendar/notes via Ovi.com

*this is a rough guide since i dont have access with my mobile phone at the moment, will improve the guide when i am able to.
*confirmed that its working... this will make my life easier in editing my contacts.
