iPhone connects to Microsoft Exchange, so you can stay up to date with your business email, calendar, and contacts. iOS 4 allows users to set up multiple Exchange ActiveSync accounts, and now works with Exchange Server 2010, giving you more ways to securely access enterprise resources.

Deployment options include support for Mobile Device Management, which enables businesses to wirelessly configure settings, monitor compliance with policies, and wipe or lock managed iPhone devices. And with wireless app distribution, businesses can securely host and distribute in-house apps directly to iPhone over Wi-Fi and 3G.
