I thought I would post this since there's no transcription up. If Heiko was there, he didn't tweet anything about it. I'm also curious to see if the iPhone app is really fixed or is it just that people are posting the iframe code in replies instead of the old embed code in the OP.
Edit: The embed code seems to be working for most people. If you're still having issues you probably need to install the lastest version of the app or otherwise unbork your device.
