It seems that after updating the iPhone to iOS4 the shelf of your iBooks app is empty, even if you already bought some ebooks. If you want to redownload these books, the store recognizes that you already purchased them but wants you to buy them again at full price.

Just to remember: with  my Kindle I can redownload any book I bought on Amazon at anytime anywhere for free! Well actually you can do this with all Kindle applications on any device, but at the Kindle itself even the 3G connection is for free. It goes even further, I actually can download any mobipocket ebook for free from the internet from any site i.e. from google docs.

Also with the Kindle you can read any  ebook purchased at Amazon on any of your devices with a Kindle app running, no matter if its a Kindle, a PC, a Mac, Android device and so on! Any device with an internet connection can instantly download your books, sync the last read position as well as bookmarks and annotations.

The conclusion: “Forget about iBook, and use Amazon Kindle and Stanza for your reading needs.”
