It's official -- Steve Jobs will introduce iCloud, "Apple's upcoming cloud services offering," iOS 5 and Mac OS X 10.7 Lion during the WWDC keynote on June 6. Note that iCloud is named specifically and referred to as "cloud services," suggesting that it's more than music.
There has been much speculation about iCloud as a music locker, streaming service and MobileMe successor. Also, developers and customers alike have been eager to see iOS 5 and we were recently led to believe that Mac OS X Lion is very close to release indeed.
It's going to be an exciting keynote, and we'll have full coverage. See you on the 6th!
