transferring contacts from iphone 3gs to iphone 4

[sd_dracula]

is there a way to easily transfer my contacts from the old iphone 3gs to the iphone 4?
i have the /private/var/mobile/Library/AddressBook addressbook file from my 3gs. can that be just transferred to the 4?

Wouldnt it just be easier to sync your contacts to outlook or windows contacts and then sync them back to the iPhone 4?

If you have both handsets infont of you, get the Bump app on both, and send all your contacts over in a matter of seconds. I done this when I upgraded my 3G to iPhone 4, worked a treat. Or you can sync them like x98car said
