This isn’t really breakings news but I am suprised at the number of people who don’t know. Steam is out on the Android and iPhone. I say iPhone and not iOS because there isn’t an iPad version out yet *I checked*. the Beta was closed and you had to ask to join, usually met the next day with a WELCOME FRIEND from steam. But as of last nights update, its open to all steam users.
This is a pretty awesome app, It has the chat client, store, access to Steam Wallet, Wishlist and all that. Sadly there is no TF2 port for the mobile platform as of yet. I love this, Steam is my primary chat client, and now its mobile! I have been using it for a little while on my old Motorola XT720 and now on my Galaxy Nexus and I haven’t had a single issue
