Where can I watch anime online with my iTouch?

I have an iPod touch 4G. I want to find an app or a website that lets me watch anime online for free. I specifically want to watch Gode Geass: R2 on it. I tried crunchyroll but it doesn't have R2, only the first 25 episodes of the first rebellion. Then I went on YouTube but the videos there are hard to find and have parts missing. On which app or website can I watch anime online for free including Code Geass: R2?
