I can't find how to join games with the latest 0.7 Pocket Edition update with an iPad and iPod over wifi. I see the realm options but I get the message "there are no more open server slots right now". Local server multiplayer is switched on for both devices.
There is no button for it anymore. Local games that have the local server option turned on automatically show up in the Worlds list of other players.
One of you should start up a world while the other stays on their Worlds list (the menu you see after pressing Play) and waits for it to appear at the bottom of the list. It should be blue in the list.
