1337pwn, who developed the Xbox Live application for iPhone (also compatible on browsers, Blackberries, etc.) recently developed a "Warhawk" scoreboard application, too.
There's not much functionality to the "Warhawk" application yet, and it's only designed for use on the iPhone and iPod Touch. You can view it through a browser just fine, though. The application is a little limited, however, because Sony doesn't have a community outreach program yet."
