Why won't my iphone 4S will not allow me to watch Yahoo videos?

My iphone 4S will not alllow me to watch Yahoo online videos. I think it might be related to Quicktime but I am not sure. I've checked with another older iphone user and they are able to see it. Any help please!


Pressing the Home button twice does not show you what apps are running. It shows you what apps were recently used.
Download a free app from the App Store. Once it downloads, your other apps should work properly again.
