I recently bought several ePub books from the Humble Bundle and from Smashing Magazine, hoping that I would be able to side load them into iBooks and then use iCloud to sync position, bookmarks, highlights and notes. I read that this should be possible here: http://blog.robertsalsbury.com/2012/08/15/ibooks-annotation-epub-and-icloud-syncing/
However after downloading the same files on my 2 devices (an iPad mini and an iPhone) this is not working. Nothing is getting synced!
Has the feature been removed, or am I missing something?
By the way I do not, nor will I ever want to, plug in my devices to my Mac. iCloud all the way for me.
Edit: I am using the latest version of iOS (6.0.1) and the latest version of iBooks (3.0.2) on both devices, and am logged in to the same iCloud account. I have some purchased books in my library and they are syncing fine.
