App for a PBF book

I have a legal PDF file of a medical textbook that followed when i purchased the book itself. The idea was so that one could view the book on a PC without having to carry the book always. I have copied the PDF file to my phone but its a pain navigating around due to the small size if the Desire's screen and the sheer number of the books pages. Can anyone make an app that automatically resizes the PDF books pages to fit my screen and allows for a better interface?

Thankyou.

Edit: the PDF file is 260mb , if that helps
