iCloud.com went live as beta site on Monday though this new portal for Apple’s big cloud-based services is still a work-in-progress. Report says that access to the site is available only to existing MobileMe customers on Mac OS X desktops and notebooks. Also, a yellow “beta” banner is still attached to the log-in screen which simply indicates a no-go for prime time.

AppleInsider says that some MobileMe users can access working apps, while others are prompted to move their existing MobileMe mail, contacts, calendar, and bookmarks over to iCloud with a popup window that appears to be not working.  Other iPad and iPhone users can access the iCloud.com page but similarly get stuck on the same “not working” screen. This could mean that the new iCloud site still have to be made available to iOS devices.

On the other hand, tablets and smartphones with Google’s Android and other non-iOS mobile operating systems can also access the “coming soon” screen prompting users to download the iOS native apps though such apps don’t exist for those devices.

At this early, it appears that iCloud.com is aimed only at developers.  It only offers a portal for users to view their iWork documents that are stored in the cloud via iCloud. And the first user reported to have successfully logged-in to Apple’s new iCloud service was Rafael Fischmann of the Brazilian MacMagazine blog, AppleInsider reports.
