Valve has released Steam Mobile for iPhone, iPod touch into the App Store. Sort of. It is available to download and install on your iOS device, but unfortunately you need to be part of a limited beta to actually begin to use it. We are sure this will change fairly soon but it is very frustrating for those gamers that use Steam and want to use the app now.
With the free Steam app for iOS, you can participate in the Steam community wherever you go. Chat with your Steam friends, browse community groups and user profiles, read the latest gaming news and stay up to date on unbeatable Steam sales.
The Steam Mobile app is available for iPhone 3GS, iPhone 4, iPhone 4S, iPod touch (3rd generation), iPod touch (4th generation) and iPad. It is not a universal binary so you are looking at 2x mode on your iPad!
