Steam App for Android and iOS devices
The App is currently in beta stage and only accesible via invitation.
Valve has launched today "Steam Mobile" app for both iOS and Android devices, but don't get too excited, it sounds better that it is because the app will only allows you to chat, read a limited gaming news feed, browsing profiles and groups and purchase Steam games. You can't play from it, for now...
The App is already downloadable from the Android Marketplace and the App Store but only a few invitees can log in as it is on testing beta stage. Anyway, if you try to log in, Valve will notice that and will send you and invite (if you are lucky enough) to test the App.
