With the announcement of the iPad came iBooks, an eReader and eBook store application for the iPad. The iBooks app uses the ePub format and will have categories ranging from “Comics & Graphic Novels” to “Cookbooks”, and possibly adult content, now forbidden in the App Store.

Yet nothing has been said about iBooks’ availability on the iPhone & iPod Touch. A sign that iBooks won’t be available for these devices, or that Apple is waiting for the right time?  What do you think?
