Apple Confirms iCloud Web Apps for Mail, Contacts, Calendar, and Find My iPhone
Will I be able to access iCloud services on the web?Apple also confirms that the existing iWeb publishing, Gallery, and iDisk services from MobileMe will not be making the transition to iCloud. Some of these functionalities will, however, be replaced and/or enhanced with the already-announced photo and cloud services in iCloud.
Yes. Web access to iCloud Mail, Contacts, Calendar, and Find My iPhone will be available at icloud.com this fall.
All existing MobileMe services will continue to be available through June 30, 2012, although some such as syncing of Mac Dashboard widgets, keychains, Dock items, and System Preferences will become unavailable if users transfer their existing MobileMe accounts to iCloud before that deadline. Other MobileMe services not transitioning to iCloud such as iWeb publishing, Gallery, and iDisk will continue to be available until June 30, 2012 regardless of whether users maintain their existing MobileMe accounts or transition them to iCloud.
