Background: I finally bought a fiction book to read on my iOS devices. It's Redshirts by John Scalzi. I bought it from Apple. It was supposed to be DRM-free but wasn't. So the author got Macmillan to send a DRM-free version to anyone who sent a copy of their purchase confirmation. So I deleted the Apple Store version and replaced with the DRM-free epub file.
Problem: My understanding was that when I stop reading on the iPad I could later pick up the iPhone and have the book open up to the place where I stopped on the iPad. But this isn't happening. I've tried placing a bookmark when I finish reading but it doesn't change anything.
Is my original assumption incorrect?
Sync Bookmarks and Sync Collections are both on in iBooks settings on the iPad and iPhone.
I haven't migrated from MobileMe to iCloud yet (still waiting for Bare Bones to get Yojimbo to sync over iCloud). Is that a problem?
Update
I switched over to iCloud and syncing still doesn't happen. My guess is it's because I have two Apple IDs the one I use to make iTunes purchases is not the .mac Apple ID that became my iCloud account.
Best Answer
iBooks uses your iTunes account to sync bookmarks and places. My wife and I share an account for app and book purchases, so I setup a separate iCloud account for her thinking that her bookmarks would go there. It turns out that I'm wrong, and it's the iTunes store account that stores it. I wish iCloud was the storage location, since the other app settings and backups do work using separate accounts.
