I found, that one of lady (Meghan Kelly) right on http://venturebeat.com that Apple is going to provide facility to exchange iPhone 4S with iPhone 5 or even you can get your money back from Apple, dependents on what is current value of your iPhone. I am not sure, how much this information is true or not, but looks like this information is not right, as information I found from Apple (USA) itself.
