Porting iphone app. If you were to start your app again from scratch what would you do differently?

I think that while "porting" is the right verb in this context, the concept may not be right. This might be an unpopular answer, but here goes.

First identify common technologies available on all platforms and try to stick with those as much as possible - OpenGL, SQLite, etc.

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.
