http://www.insanelygreattees.com/news/?p=51 works pretty easy - text from their site 'Filemark Maker - put files on your iPhone JULY 19TH, 2007 BY DAVID Filemarks let you store high res images, text files, and PDFs on an iPhone! There arent any good ways to do this with the built in Apple tools - you can use iPhoto to copy images, but theyll be scaled down and become unreadable. If you want to read a pdf on your phone, you have to either email it to yourself or browse to it in Safari. Filemarks store your files data inside a bookmark. When you want to view your file, you open the bookmark in Safari on the iPhone and you can view it, whether your phone is online or offline."
