It shouldn't be necessary to post this, but already I see screen shots posted from the simulator, etc. Think twice before posting screen shots, excerpts from developer documentation, details that have not been publicly released, etc. It's a violation of your developer agreement, and could get you booted from the program or worse. Just a word to the wise. Not only is it a violation, but you're publicly documenting it. (Downloading the SDK now, so I'll be shutting up with any speculation, as what I read would almost certainly leak through no matter how hard I try...) You still want to do it - hey, it's up to you. The rest of us thank you for putting the info into the public so that it can be discussed.
