iPhone iCal behavior with expired SSL certs?

[gettyless]

Does iCal break when your "real" SSL cert expires? I want/need to access my personal Zimbra calendars from my own non-work server via iPhone's iCal which is too stupid to work with self-signed certs:

In other words, when it expires, I hope the iCal on my iPhone still allows me to view my calendar without much fuss. I suppose I can set this up myself as a test but it's not that ultra urgent so I'd rather harness the power of the collective Zimbra hive mind.

Wait nevermind... I didn't know about the trick to first accept the self-signed cert with Safari:

...though, I need to verify this with the Safari and iCal on the iPhone. I hope this works so I don't have to pay for a "real" SSL cert.

Hmm another piece of the puzzle that I had no idea about. This makes it sound like you can get away with self-signed certs after all. I figure I'll note this in case someone else goes down the same path:

Note: The iPhone prefers non-selfsigned SSL connections. If you have a self signed certificate, then it would be a good idea to install the iPhone Configuration Utility to deply a self signed certificate on the iPhone: Apple - Support - iPhone - Enterprise
