Google has announced that they have received permissions to use Gmail as the branding for their webmail service.
Google has been using Google Mail as the Gmail branding in Germany due to trademark issues.
Users of course got their email id with @googlemail.com address though their user ids worked with both @gmail.com and @googlemail.com.
Google said that they would soon start alerting their German users about the development. They would be able to officially start using @gmail.com as their primary email if they want to!
