Stating the obvious here, but WHO CARES? I'm pretty sure no religion states you will have access to Apple services when you die....
It's like asking what will happen to your clothes, house, car even. Bed?
And if Facebook is asking you what you want done with all your photos when you die, then it's even more reason to never have an account with them as far as I'm concerned!
And I would also say you posted this in the wrong forum? Think their is an iTunes forum on here?
