Mobile Gateway & iPhone
Synchronica has released an update to its Mobile Gateway software, currently at v3.0, which now includes support for the Apple iPhone. The software synchronizes phones with Microsoft Exchange servers to retrieve e-mail -- importantly, however, it does not require an organization to configure IMAP, the protocol accepted by the iPhone. Rather it makes use of Outlook Web Access to send messages directly to the iPhone's mail client, where it is also integrated with the address book. Licenses for Mobile Gateway start at $1,650 for five users.

live demo
Went to look at the live demo, and it was asking for my login and password to my exchange email account. I'm not sure how this will work, but giving a third party your login info to work email, even OWA is a big no-no in my mind.
