I have tryed and can't find an app or website that I can watch game of thrones on that supports the iPhone 4s

I keep seeing ads on HBO saying you can sign up for HBO-Go, which will let you watch any and all episodes of any HBO show on tablets, mobile devices, and I guess phones too. You do need to subscribe to HBO through your cable company, though. Try going to HBO.com and look for a link to HBO-Go and see what the requirements are.
