Apple added this enterprise support page, titled AppleCare for Enterprise, to their web site.

Because Apple makes the hardware, operating system, and many applications for every Apple product, AppleCare for Enterprise delivers integrated support and service you can’t get anywhere else. You’ll get IT department–level support by phone or email for all Apple hardware and software. We’ll provide support for complex deployment and integration scenarios, including MDM and Active Directory. And if you need help with IBM MobileFirst for iOS apps, we’ll help troubleshoot your solution and work with IBM to get your issue resolved.

AppleCare for Enterprise provides IT department–level support for six technical contacts you designate. Support is available 24/7 with one-hour response times for top-priority issues, such as when a production service is down. You can also increase the number of technical contacts for an additional fee.
