I have an iPhone 4S & have had it since the 4S was first released. I haven't done anything w/photos or camera, etc. Today I wanted to take pictures w/the phone but I don't have a camera icon on the phone. I went into iTunes and looked at all of the apps I have for my iPhone - installed and not installed - and Camera isn't listed anywhere. Where is it, how do I find it, how do I get the app? Any ideas as to why I don't have Camera?
