As Google Authenticator is only available for IOS, Android and BlackBerry OS I started looking if anyone ported the software to Symbian S60v5 or J2ME (for feature phones) and found this:

It's Google Authenticator ported to J2ME, so you'll be able to add extra security to your account without the need of one of the most common operating systems
Just install the jar file in your phone, add the new key (the key you find in your account management) and you'll be getting the security code
PS: I tested it and it works perfectly!
