Going by mine (still running iOS 5.1.1 'cos I don't like Apple Maps, since having Google Maps was main I bought it + my iPod Touch before it)......... Facebook app (old version) still works, but the Phone + OS is too old to install & run Facebook messenger. Twitter app (old version) still works Instagram.... never been able to get the thing to work on my iPhone, but "earlier compatible version" seems to work fine on my iPad that's still running iOS 5.1 (don't like Apple maps, or the new icons on latest iOS) Youtube quit working ages ago on it (same with my first gen Apple TV + iPad), and the new app won't install either (and supposed to be pants anyway). UK National Lottery app doesn't work any more... tries to force an update on me, but update not compatible.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
