I can read on Mobile collaboration tools for enterprise messaging for mobile devices that it exist four ways of synchronizing a iPhone with Zimbra.

The first one, Zimbra Mobile for iPhone, where can I download it?

Am a new administrator here at our company that has a Professional License from Zimbra. We also have bought a bunch of Zimbra Mobile licenses according to the previous administrator. So where is this Zimbra Mobile? What am I missing here? Does the previous administrator has download links in his mailbox? Maybe "Zimbra Mobile for iPhone" ain't something that should be downloaded?

I have also read IPhone - Zimbra :: Wiki which explains how to sync iPhone with ActiveSync. Is this the "Zimbra Mobile for iPhone"?
