The Saudi Center of Excellence in Information Assurance (COEIA – King Saud University) has released a couple of Arabic electronic books for the iPhone and iPad.
The books can be downloaded either as an Adobe PDF or ePub file and then added to the iBooks app on the iPhone, iPad or iPod touch. You will need a US iTunes Store account to download the books from the iBookstore. Of course these books are free.
