Apple has officially opened its iCloud Beta portal to developers enrolled in the iOS 6 beta. MacRumors reports that the site, which is located at beta.icloud.com and was spotted briefly in early May, offers previews of new Calendar functionality, as well as a redesigned Find My iPhone web app, and all-new Notes and Reminders apps. The new apps most mirror the functionality of their iOS counterparts, with the new Find My iPhone tool adding a battery status icon and support for the upcoming “Lost Mode.” The new iCloud web app suite is expected to see a public rollout alongside the release of iOS 6 this fall.
