Since the keynote was all about iPhone, and they spoke about 3 things (SDK, enterprise, new features), did the 2 Golden Gate bridges depicted in the WWDC'08 banners & promos have any relevance after all??
I believe the banner was for WWDC in general and not just the keynote. Even though the main speech was limited to iPhone development, there's much more to the conference, related to developing for both Mac and the iPhone.
