The pages for all the MobileNavigator apps in iTunes show that you need iOS 3.0 or later. Since the very first iPad's shipped with iOS 3.2 you should be alright. Every single iPad operating system is supported so you should have no problems with it.
Hope that helps :D.
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.
