iOS 4 Brings Support for Snow Leopard Server Calendar and Address Book Services

Daniel Eran Dilger at Apple Insider:

Support for Calendar data store access from the new Calendar Event Kit, enabling apps to create and work with event information. Apple also now supports CalDAV-compliant account sync in Calendar (used by Mac OS X Server’s Calendar Server) and CardDAV-compliant account sync in Contacts (used by Address Book Server). Developers can also incorporate SMS features into their apps, add Quick Look support, and use improvements to Map Kit for drawing routes or adding overlays to map views they embed in their apps.

For small businesses wanting to go all-Apple, this is a huge selling point for Mac OS X Server.

iOS 4 should be out today for existing iPhone and iPod touch owners.
