How to put back all the calendars

I've seen several people do this with Google Calendar -- don't use Gmail Calendar Sync, use gsyncit.

Looks like I may have a solution, according to Lifehacker

"If you set up your Google Calendar to sync using CalDAV, the calendar colors sync seamlessly between your iOS device and Google Calendar. If you add a calendar or change a calendar color on Gcal, the colors will sync to your device. Just turn off calendar sync on your Exchange account, and enable it via CalDAV."
