Another thing I was told all x360s have an electronic serial number thats what links you to your Xbox live account and the market place. and if they end up giving you another 360 because it was cheaper than repairing yours then you have to buy all those things you got from the market place they will NOT give you credit to redownload them. That is not right. You spend hundreds of dollars on a 360 to find out its defective due to manufacturing then you could have spent who knows how much on the online market place only to find out its all lost. Yay for public relations and customer support.
