That's awesome, I've been a heavy user of multiple calendars for a long time and absolutely hated being stuck to a single one. Though it's horrifyingly non-discoverable. Another help file[1] mentions this page though, which you can visit with any browser: https://www.google.com/calendar/iphoneselect

edit: the iphoneselect link seems to be working for me, though my iOS calendar is all kinds of screwed up at the moment, so I can't say if it's 100% bug free or not. I have thousands of repeat birthdays for no reason I can detect, but that was before changing those settings :|
