IE & Google Chrome For Iphone

I just downloaded Google Chrome - the new web browser - on my laptop. It works well even though there are few things that are missing. But I am quite sure more features are coming as Google Chrome moves ahead in its beta test stages. I just checked out the Apple Itunes App Store but couldn't find Google Chrome App for download. I would also like to download Internet Explorer on my Iphone because some sites only open with Microsoft IE. Hopefully, Microsoft and Google will team up with Apple and release these two web browsers for Iphone.
