Google Calendar not showing up on iPhone

I'm trying to get me iCal and Google Calendar to sync. I've set up my gCal in iCal using the CalDAV instructions and now my gCal shows up in iCal, but as a separate calendar, not really what I consider syncing with my actual iCal "home" calendar.

The other thing is that the gCal won't show up on my iPhone at all. I'm confused about this because I've read several post of people saying their gCal show up but as read only. Is this true?

Am I missing something? Has anyone gotten their gCal to show up on the iPhone using the CalDAV method?
