All you need to do is to setup a sync profile with these simple steps and it’s good to go. You have to manually trigger the sync though, but that’s just fine by me since the battery life for my E66 is average at best.

A quick note, contacts synchronised through this method will show up in the “My Contacts” group in your Gmail contacts. If you want to add a contact to your phone, it has to also go into the same “My Contacts” group.

What I love most about this setup is that it allows me to easily edit or add contacts through my Gmail account. Way faster than fiddling around with the phone.

This method works only for Contacts. If you need to sync up your calendar as well, there is a somewhat more involved method documented here.
