Is there a way to transfer all of your MobileMe contacts to Google Contacts?

"Assuming you have a Mac, and you're syncing MobileMe contacts to your Address Book:

Open up Address Book, highlight all your contacts, then click File > Export > Export vCard. Save the resulting vCard archive somewhere. Open up http://google.com/contacts, click Import > Choose File, and select your archive.

If you have Windows, just export your contacts as a CSV or vCard archive from Outlook/Outlook Express/Windows Contacts and import them in the same manner.

You could also try importing through Gmail using Settings > Accounts and Imports > Import Mail and Contacts, and then entering your MobileMe information."

This worked well! Actually, it was even easier than your full instructions indicated. I followed your instructions exactly about opening Address Book, selecting the contacts I wanted to export, then clicking File > Export > Export V-Card. Next, I signed into my Gmail account, and all the contacts I had highlighted to export just showed up in my Gmail "Contacts" list without my having to do anything further.
