Apple has detailed a series of recent changes to MobileMe, its online hosting and sync service. Many of these are iPhone related, for instance allowing iPhone 3GS owners to upload a video to a Gallery album, or if no album exists, create a new one automatically. Contacts and calendars can be merged on the first sync of an iPhone or iPod touch, and when deleting a MobileMe account or disabling sync, handheld devices retain information. This includes associations between ringtones and contacts.

Handheld users are now also able to search through mail messages stored in the MobileMe cloud. General e-mail changes include an unread messages count next to each folder, and the retention of HTML formatting when forwarding or replying. In the desktop Mail client, aliases should be displayed correctly.

Windows users have been given the ability to sync via a proxy server, while Mac owners can now use Back to My Mac without knowing the other computer's username and password. Mac OS X 10.5.7 is required, and connecting systems may be forced to sign back into MobileMe for changes to take effect.

Some problems with accounts and iDisk have lastly been resolved, such as unrecognized e-mail addresses when filesharing. Separate active accounts can be newly subsumed under Family Pack licensing, becoming sub-accounts.
