Gmail.com addresses being rolled out in Germany
 

Having settled its differences with the German trademark holder, Google can finally bring Teutonic communicators over to gmail.com addresses. As with the other countries that have previously made the switch, your @googlemail.com (or .de) address will remain valid, all you have to do to make the switch is respond to the prompt when it appears in your inbox.
