Quoted from JayLar:
I am seriously considering this as well, as the game is so damn hard. Just too bad having to play the game any other way Pat intended too.
Maybe the code update will make sim memory on factory standard?
I always have SIM card save on; you are right, the game is too hard without it. You'd never make it to the end without having that on - it's hard enough to earn the darn things!
