If you’re going to the keynote in person, print out the bingo card and play along live. The first person in the audience to win the game is expected to yell “BINGO!” loud enough so that the rest of us can hear it when we watch the keynote webcast video later.
The PDF is a must download. I will do this when I watch the video later. I will also pay attention to any yell while watching the video.
I think Apple will hold an event (possibly in Paris?) for non-Mac stuff. It’s the developer conference. If there’s no iPhone SDK, there’s not much to talk about in WWDC regarding iPhone, I suppose.
