Steam Mobile, which was first released last January, just put out an update to adapt to the iPhone 5.

Rather than only make accommodations for the larger screen, Valve made sure that this new version of Steam Mobile was lean, mean, and free of the many technical issues that plagued the last version. If you already have a Steam account, linking it up to the app should be a breeze this time.

With Steam Mobile, you can chat with your friends, purchase games, and stay up to date on gaming news. Plus, it's Valve. They pretty much laid out the blueprints for digital downloading. Even if you don't think you'll use it, the app is worth downloading for the sake of the weird, Steam/App Store nexus of the universe thing that's going on.
