Bad news for Blackberry and Windows Mobile, by the looks of it. According to Phil Schiller, big firms wanted the moon on a stick:

Push email. Great calendar integration – pushed to them over the air all day long. Push contacts. Global address lists. Additional VPN types, including Cisco IPsec VPN. Two-factor authentication, certificates and identities. Enterprise-class Wi-Fi, with WPA2/802.1x. Tools to enforce security policies. Tools to help them configure thousands of devices as they deploy iPhones and set them up automatically. And they want the ability to protect that data by remotely wiping it.

“That’s a long list of important features,” Schiller says. “They say if we just did these things, it would really help adoption in the enterprise. And we’re doing all of these things in the next release of the iPhone software.”
