Phone contacts to Gmail

they should sync automatically but if they dont then you can go in to your contacts app and choose to export contacts to sd card then go to the gmail website and go to contacts. there will be a button above all your contacts that says more actions and one of them is import contacts. then you can import the csv file that came from your phone. hope that makes sense
if you export the phone contacts and import them into gmail, you may want to hide the phone contacts so they dont show up as dups.
