Old Address(URL)

When I first setup WP months ago, I installed it at not.sniper8.com. A short time later, I changed all of the settings I knew about to sperolaus.com. It worked and works fine except that google only recognizes it as not.sniper8.com and when I look at the status bar during page loads, it says not.sniper8.com. not.sniper8.com is one of my valid subdomains still, but I changed all my known settings to sperolaus.com. Also, last week, I upgraded to 1.2.1 without any hassle, but that didn’t change anything. I searched my database with phpmyadmin, but it didn’t come up with anything in the tables. I’m at a loss.
