If you run your app through Instruments, and there don't appear to be any memory leaks, you're probably okay. Make sure to thoroughly test the application, to cover as many scenarios and as much code as possible.
It is possible that some memory leaks to be present when tested on a real device. Since the firmware of the device is different than of the simulator, and also due to the fact that simulator is a software, that won't always be perfect as andy suggested, you have to test for memory leaks in the device itself before submitting. Simulator may not always catch all the memory leaks.
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.
