Steam hasn't forgotten about the remaining Windows Phone faithful. It just seemed that way, with folks on Android and iOS getting a mobile app way back in 2012. The Windows Store listing says that you'll be able to use Stream Guard's authentication system, trade and sell items, keep an eye on the game marketplace and remote download and install games to your PC via the application. Just in time for this year's summer sale; how about that?
