I want to read eBooks on my iPhone 4. Those eBooks are heavy on mathematical formulas and sometimes diagrams. I have some problems though:
When I convert PDFs and DJVU to ePub format and download the ePub file to iPhone, then I open it with Stanza, mathematical equations do not show correctly.
When I open PDFs and DJVUs using Stanza without converting to ePub format, the text appears fuzzy and when I zoom in or out I lose the ability to flip through the pages – and I can't change or close the book.
