Its a pain that I still can't get it. I always bought unlocked phones so I didn't have to wait around for updates.
Is there a way to get the update manually that doesn't void the warranty etc so I'm not waiting around for who knows how long?
Amazon might also sell things from grey import so its kinda hard to judge if its a German phone based on that. You might however try to enforce the update by checking manually. (There is also some delay on that to prevent everyone from updating at the same time, but after the release is set - You should be able to enforce it inside a week).
