How do you sync your Outlook contacts with Gmail?

"You can use the free Google tool Google Apps Sync for Microsoft Outlook :

Google Apps Sync synchronizes nearly
all of your personal contact
information between Outlook and the
Google Apps interface so you can reach
colleagues, family, and other contacts
from either interface.

You can download it from here.

You may also use file export and import, as described in:
Merge your Outlook and Gmail contacts"

"KiGoo - Manage Google Calendar and Contacts through the Microsoft Outlook interface.

KiGoo is shareware, try before you buy."

As well there is tool calling Outlook4Gmail. It's freeware in basic version but it's enough to sync your contacts.
