is there a pdf viewer for a psp 3.71?

Question

if so please email me the download site and step by step instructions

Answer 1

you can only download aps like pdf viewers for homebrew enabled PSPs
your PSP has to be version 3.50 or lower to downgrade it to 1.50 then upgrade it.
So im afraid the answer is no
although you could take screenshots of the pdf and save then under PHOTO
