Currently my wife and I both have the iPhone 4 and have upgrades available. We are discussing how we want to use those after they announce the 5S/C. Right now she wants the 5 which I assume will follow the usual pricing structure and drop from $200 to $100. I have a book book case and plan on getting the 4S which should become the default 'free' phone. Does anyone know when these price changes occur or if they do announce the C will I even have an option to get the 4S?
