When i bought my N900 i immediately set it up to sync the calendar and contacts with Google, using MfE. This worked because I immediately had all my contacts and appointments. I have also set up a few IM accounts and started merging contacts from the IM accounts with my normal contacts. But now it seems that whenever i sync with Google, existing contacts don't seem to be updated. So now i'm thinking about trying some different other options, but i'm not sure which one to try first. I would like that my existing contacts are updated (obviously) if i modify them, and also i'm wondering if one of the solutions can sync the more 'special' fields like Birthday, IM-accounts etc. I'm thinking about trying NuevaSync (with MfE) and SyncEvolution. Does any of the 2 support those extra fields?

This weekend i tried NuevaSync to sync using MfE, but i have some problems with it. Syncing my Google calendar with it works perfectly. And although it doesn't give any errors in while synching my contacts, it doesn't seem to do anything with my contacts. In Google I had 146 contacts, which were already in my phone before setting up NuevaSync. After setting up Nueva and doing a full resync, i added a contact in Google Contacts. Then i hit the manual sync button on my n900, but the contact was not added to my phone. I also tried it the other way but again the new contact was not synced from my phone to google contacts. Am i doing something wrong here? Should i maybe delete all my contacts on the phone and start over with a fresh nueva sync?

And another question about NuevaSync: Will it also synchronize 'extra' fields, such as birthday, IM-accounts, notes,..., to Google?
