iCloud Logo Revealed as Moscone Center Prepped for WWDC
The image below was captured by Doug Bowman and posted to TwitPic.
Another banner, captured by AppleInsider, shows an image of a lion, a plus sign, the number 5, another plus sign, and the iCloud logo. That refers to Mac OS X 10.7 Lion, iOS 5, and iCloud, all of which will be discussed on Monday.
It seems also that iCloud will be replacing MobileMe completely, as has been rumored of late. Earlier reports pointed to iCloud being part of a revamped MobileMe, but that doesn't seem to be the case any longer.
