First. I have tried every trick in the (non hacked)book to read PDF books / files on my iphone. About the only feature I wish it shipped with other then a "delete all email" button and to do lists, is a PDF reader. One that saves the last page I am on and is fast in that it does not have to load the whole thing in like email tricks do. So I just realized. If apple does not ship one by then, I am sure (since it will be relatively easy I hope.) we will soon have our PDF book reader once the SDK ships! Yes!
