App on iPhone to read Naruto Shippuden?

What is a good app on the iPhone to read Naruto Shippuden? It doesn't have to be free, but I'd prefer free. I'd also like an app that doesn't require me to download the manga.

I did a search for manga apps on Appolicious and here are some manga apps owned by our app-loving community:

Manga Depot: http://www.appolicious.com/omg/apps/1102…
OZ: The Manga #1: http://www.appolicious.com/shine/apps/79…
i Manga X Free: http://www.appolicious.com/shine/apps/12…

or Manga Rock! Very solid, have a good selection of manga! It even allows you to download manga and read later.
