With all the reading, rumors, and speculation going on I just want to ask a question of all you concerning older generation iPhones. Most of the information out there points towards Apple producing two phones, the iPhone 5 and the cheaper iPhone 4. Please allow me to speculate and say that if the new, cheaper iPhone 4 hits the market at $99, and the iPhone 5 takes over the $199 spot, what will/could happen to the current iPhone 4 models left in stock by the carriers? I've never fully understood what Apple does with the older units when they release a new model. Do you think it will still be offered for sale by the carriers? Thanks!
