yes you sure can sync all three as long as they all are on the same kindle store account name. Have you tried going to your iphone kindle app and clicking on the sync function there on it and seeing if you can get it to sync and add the new books? I do not have the iphone but that is how it worked for my laptop, I had to go to the kindle app on it and click there to sync and find new items, then go to the archive area on that kindle app and double click on each to get it downloaded to there. I know it says it can be synced with the iphone and my nephew has both and did it so if you play around with it you should be able to do it. Try going to the Menu on your kindle pc, then the manage my account to see if you can click from there on each individual listed book in the drop down beside them and select your iphone app there. I am able to do my sync that way also. "For Whispernet synchronization to work, however, you must keep it turned on in your account settings on the Amazon site (it's on by default)--and, of course, you must turn on the wireless support on your Kindle devices. The option of turning sync on or off is useful, because if more than one person is reading a book registered to a single account at the same time, they probably don't want to use one another's bookmarks. But if you're the only account user, turning sync on lets you pick up reading on any Kindle device or application. "

Thanks, Raven. I got the free one and bought the other 2 for $.99 each. I really like books that are a series, because sometimes I like the characters in a book and am sorry when I have finished it.

I have been guilty of the same thing I love pixel of ink. Plus I also have a ton of ebooks in epub format too. I have no idea how I will read them all. So many great free books I don't know why I would need to buy any.
