What's the best PDF reader for the iPhone? I'm curious as to why Adobe has not released anything yet?

I think iPhone can read PDFs as built-in functionality.

All you need is an app which will let you transfer PDFs over in order to view them, or you can e-mail PDFs to yourself and view them from the built-in Mail app.

The app that I have which does this is called "Air Sharing", but I think you can get free alternatives too.

This is one way to do it. But really, do I need to download the pdf every time? – Brian Jul 15 '09 at 15:15
No, if you use Air Sharing, you just transfer the PDF to your iPhone once. Then using the Air Sharing file explorer you can browse to the PDF and view it. – Rick Jul 15 '09 at 15:25
Air Sharing also remembers your place in the PDFs, which makes it head and shoulders above reading via MobileSafari. – bbrown Jul 15 '09 at 18:02
So what free program is there that will do what "Air Sharing" does? – Neil Jul 31 '09 at 19:32
Reading the description of the "Files lite" app, it seems to be similar to Air Sharing. – Rick Aug 6 '09 at 10:25

GoodReader supports passwords, large files and advanced reading & scrolling options.

I second GoodReader - it is the only PDF reader that I have tried that can handler larger PDFS (> 20 mb) without trouble as I believe it only loads a page at a time into memory instead of the whole file. – Russ Cam Aug 18 '09 at 8:02
I'll take off the answer for now to see more results. – Brian Aug 18 '09 at 14:30
I'd second GoodReader as well. for very large PDFs ist has been the only solution for me, having tried out different other apps incl. the ones mentioned below (as of 13.09.09) – Wolf Sep 13 '09 at 13:22

Discover is a free app similar to Air Sharing. It lets you to transfer files to another iPhone, and allows you to view a lot of different file formats on the phone.

PDFs are built right into the operating system and so any program that is enabled to can show a PDF in a UIWebView (so good examples are applications like Safari or Mail).

This is obvious. I was looking for something that can open and close pdfs on the filesystem. Rick's answer works. – Brian Jul 28 '09 at 3:19
