I have this book I bought that is in an app used for offline reading. I don't want to use the app for offline reading. I want to read the book/content separately on my iDevice or Mac etc. I am not sure what format it would be in inside the app but there is obviously an entire book in the app. If I use an iOS file system utility would I be able to extract it out? I used an iOS file browser and go to the images used inside the book BUT can't seem to find the actual pages of the book. I think I will need to jailbreak to access some hidden files?
