I have a KT and a replacement KT. Put all my books on the new one. Went to read my current book on the new (replacement KT), starts on page 1. Whispersync is ON, "Go to further page read" says I am on the furthest page (1). Same thing happens with my iPhone Kindle app. Anything I read on my KT and then try to read later on my phone, doesn't pick up where I left off. It used to when I had a k3, but not anymore with KT. Seems that it doesn't communicate with any other device. This is really annoying since I have had so many problems with this touch. And this is supposed to be better? Now I have to go check my other touch to see where I left off and then try to find that on the other touch? I thought all of this was supposed to sync through whispersync Argh!!! How do I fix this??
