Apple to Launch iCloud, iOS 5, and Mac OS X Lion on June 6th

This time, Apple’s Worldwide Developers Conference is all about software and services, and we’ll be there when Steve Jobs will kick things off on 10 AM PT June 6th. On tap: iCloud, Mac OS X Lion, and iOS 5. Read on for a quick preview.

This is the first time Apple has confirmed that its “upcoming cloud services offering” is called iCloud. Many expect iCloud to integrate aspects of MobileMe and iTunes, finally allowing users to cut the USB cord. Based on reports that Apple has struck deals with most of the music labels, we’re assuming iCloud will give users permission to stream tunes they’ve already purchased from iTunes without having to upload them again (unlike Music Beta by Google and Amazon Cloud Locker).

Another pillar of the WWDC keynote will be Mac OS X Lion, which is the next generation of Apple’s notebook and desktop operating system. As you’ll see in our Lion preview, will feature richer multitouch gestures, an iOS-like LaunchPad for launching and organizing apps, and more. There’s a rumor than Apple will showcase Lion by releasing new MacBook Airs equipped with Intel Sandy Bridge processors, so it’s possible that Apple will debut them at WWDC. In fact, 9 to 5 Mac is reporting that MacBook air supplies are constrained ahead of a summer refresh, just in time for back to school.

Last but certainly not least is iOS 5, the software that powers the iPad, iPhone, and iPod touch. Not much is known about the upcoming OS, but it’s safe to assume that it will integrate tightly with iCloud. And if you believe the leaked videos, iOS 5 may also take a new approach to multitasking. We’re also hoping that the software takes a new approach to notifications and that the OS ties in better with social networks. Android already does.

Stay tuned for all the announcements and our hands-on impressions at WWDC.
