Apple has unveiled the beta for iCloud, the company’s new suite of media streaming and cloud-based services.

The new beta, which is available to all users with an Apple ID, features web-based version of Mail, Contacts, Calendar, Find my iPhone and iWork. They are accessible if you visit iCloud.com while using iOS 5 (available to Apple developers) or Mac OS X Lion. It does not include Apple’s cloud music services, including iTunes Match.

Update: Some of our readers are having trouble accessing iCloud with Lion.

Apple also unveiled the pricing structure for iCloud. The first 5 GB of storage on the service are free. An additional 10 GB will cost $20, 20 GB will cost $40 and 5 0GB will retail for $100. It’s more expensive than Amazon Cloud Drive, which gives 20 GB of space for $20 and lets users store an unlimited amount of music for free.

We’re playing around with the iCloud beta now, and while we’ll have more to report, our initial conclusion is that the iCloud beta is a modified version of MobileMe. It includes similar interfaces, which isn’t a surprise. The addition of iWork support is a welcomed addition though, as is the simplistic and universal interface for all of Apple’s cloud services.

We’ve taken some screenshots of the beta and embedded them below. Check them out, and let us know what you think of the iCloud beta in the comments.

Apple will start its annual Worldwide Developers Conference (WWDC) with several important software releases: iCloud, Apple’s upcoming cloud service, as well as the next iteration of its desktop and mobile platform, Mac OS X Lion and iOS 5.

Apple announced earlier that the focus of this year’s WWDC will be software, in particular iOS and Lion, and recent rumors claim that the next generation iPhone will not be announced at the event.

The really big announcement this year is iCloud, which is rumored to be Apple’s cloud service for music. In an announcement Tuesday morning, Apple confirmed that iCloud is coming as a “cloud services offering” but didn’t mention music or provide details. Recent reports said that Apple has signed a licensing deal with EMI and was close to signing similar deals with Sony and Universal, which would pave the way for iCloud. Apple’s music offering comes hot on the heals of announcements of similar services from Google and Amazon.
