Dropbox is another highly recommended app... if you don't or can't open a pdf in the browser or import it via iTunes, you can put them all in dropbox on your PC, then anytime... connect to your free dropbox account and download what you want... not just pdf's but pictures, documents, other things.
BUT... dropbox has to be installed on PC too.
