Following the official launch of MobileMe late last week a knowledge base article on Apple’s support site began raising concerns amongst some.

The article outlines that instant data sync only occurs to MobileMe from the web interface or a portable device such as iPhone or iPod touch. The main concern is that changes made on a Mac will not be instantly synced back to MobileMe but changes will be updated automatically every 15 minutes or manually by hitting the “Sync” button.

Also regarding MobileMe, Apple has confirmed that the iDisk File Sharing feature of the service will be delayed.

In response to a customers support email “Mike” of Apple’s MobileMe Support team wrote, “When MobileMe was announced, iDisk File Sharing was mentioned as a feature; however, the MobileMe webpage noted that all features listed on that page were subject to change,” continuing, “When MobileMe was released on July 10, 2008, iDisk File Sharing was not included. I apologize for any inconvenience.”

Apple’s website lists iDisk as coming soon but doesn’t offer any timeline as to when the feature will be enabled.

To help some users, Apple has pointed many users towards this support article, which describes other ways in which MobileMe users can share the contents of their remote iDisks.
