So Apple is prepping its space for WWDC 2011, which is on Monday, June 6th and inside they area already preparing the decorations and signs and low and behold someone took a shot of what looks to be the icon for iCloud. Also next to it is an icon with just a 5, presumably, for iOS 5 and a Lion, which we all know stands for OS X Lion, so it looks like Lion + iOS 5 + the Cloud = WWDC. Anyway, thanks to Apple Insider for posting the pictures.
