When loading ePub book to Goodread, you can select it and through File management , open it with the "....Open In " special button .it's being automatically transfer to iBook. I do have the Amazon Mobi application on my iPad, but the "...Open In" doesn't work. Goodread does not recognize Mobi file type. Any idea? Any one ? Is ther a way to transfer Mobi eBook directly to the Amazon application?
