Not that I am aware of. There are a few threads of people who have found a way with the Kindle and side-loaded ebooks. The most success I have had is reading a side loaded ebook on my kindle, remembering the location I was up to and going to that location when out and about on my phone or ipod. I havent seen any option of a go-to-page with the Kobo app so I don't know if that is possible at all (and nook, well I'm in Australia so I'm not wasting my time).
Not quite automatic syncing but better than nothing.
