I notice that in the preferences section of the web client, a new 'Mobile Devices' sections shows up, listing my iPhone and stating 'needs provisioning'

I assume that once provisioned, remote wipe will be possible.
So I installed the iPhone Configuration Utility and made a mobileconfig that would configure the mail settings and deployed it to the phone.

The phone still shows as unprovisioned though. I see a "configuration profiles" and "provisioning profiles" in the apple utility, but cant workout how to convert the config profile I've made, into the needed provisioning profile.

Has anyone done this?
Or, given the new code in zimbra, how what method does zimbra want me to do to change the "needs provisioning" message to "Provisioned OK" ?
