My next test is to email it ONLY to the K4, then use Amazon's Manage My Kindle page and use 'Deliver to…' to send it to my iPad and iPhone, see if that works.

It's seems to be simply 'flaky', or I'm doing something wrong. There is definitely not a connection issue, I have a solid internet connection, and anyway, I tried it on more than 1 wireless network. I deleted the book and re-converted it to mobi in Calibre, then did the single email/3 recipients thing again - this time, still not working, except for once just once, flicking forward some pages, my K4 came up saying the last page was iPad 2. Remember, it's the SAME book, I haven't re-emailed it or anything, it's the same file that WAS working a few days ago. Done some more testing, same tests as before, definitely not working - neither the iPhone 4, iPad 2 or K4 are syncing the last page. I closed the book, then checked it on the K4, and it HADN'T picked up the last page read as being the iPhone. Well, perfect except one thing - a few days later I was reading the same book on iPhone, and noticed the sync button WITHIN the book (not the one at the Kindle app main page) was greyed out. Read a few pages on iPad, close book, go back to K4, told me last page read was iPad. Progress a few pages on iPhone, close book, open it on iPad, told me last read page was on iPhone 4. After a good few tests, Whispersync was clearly working - go to a page on K4, press Home, immediately try book on iPhone 4, told me latest page read was on K4. I then tried a single email, with 3 recipients (my Kindle address, iPad address, iPhone address), with the same book as an attachment. I tried creating 3 emails, one per device, with the same book as an attachment. I have some books in Calibre, converted to mobi. #1 gers1978 01-15-2012, 10:06 AMAs I understand it, Whispersync is now possible between a Kindle (in my case Kindle 4) and the various iOS apps.Īmazon has assigned a unique email address to each device.
