The 3gs to 4 makes more sense because you can buy the 3gs or the 4. If you have the 3g you already know what it can do. The important question is if I am upgrading should I be getting the 3gs or the 4.
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.
