Crews have already begun putting up WWDC decorations at the Moscone Center in San Francisco, photos show. A team began applying company logos to the building's exterior yesterday, in keeping with normal Apple plans. Moscone staff are also likely raising banners and setting up other material inside, but these were not immediately visible. WWDC 2011 is only set to begin on Monday, June 6th, leading off with a Steve Jobs keynote.
