Booksstand is a Cydia Tweak that will put your dusty old Newsstand to use by creating book shortcuts. Instead of subscriptions, your Newsstand can now hold your favorite books for quick referencing. After installing, open up iBooks, tap edit, choose a book or two, tap move, and choose Booksstand. This will add the items you selected to your Newsstand when you can just tap the cover art to open the book! If you aren't big on subscriptions but read some books or PDFs on your iDevice, this is perfect for you. Booksstand can be found in the Cydia Store for $.99 under the Big Boss repo.
