It is Chris, renegade iPhone scientist, again bringing you the latest! Even though my Docs To Go posts drew almost blank stares, I am back to tell you:

You can now send invites from an iPhone using the OS 3.0 software. Now keep in mind this ONLY seems to work with the primary calendar in Zimbra. If you select to put the event in any of your other personal calendars, the invites just fall off the event.

But it does work, where once not but hours ago it did not!
