How to move phone contacts to Google? When I create a contact on my Android phone, I can choose to store it to the SIM, the phone or to Google.  If I choose phone, is there an easy way that I can move or copy that contact to Google (so it shows up in GMail, for example) at some later time?

EDIT: I'm using the Samsung Vibrant, T-Mobile's variant of the Galaxy S, running Android 2.1.  The edit menu for contacts shows options for Edit, Delete, Link contact, Mark as default, Send namecard via and Copy to SIM.
This is the simplest way that I found to do it with my Samsung Galaxy S:


From the main Contacts screen, hit Menu, then More, then Import/Export, then Export to SD card.
Connect the phone to the PC and mount the phone's SD card as a removable drive.
Open browser to GMail, select Contacts then Import.  Select the file on the phone's SD card, then Import.  


Voila!  On the next sync, they're back as my phone as Google contacts.
