I've spoken to Microsoft today in regards to replacing my dead 360. I've received the email from Microsoft and the shipping label from UPS. The guy on the phone told me to disconnect all components and place it in a separate box, not the original one. That's been done, but I am also sure he said to write down the code he gave me over the phone on the shipping label. But I see nowhere to write it. So for anyone who has returned their 360, where on the label do you write it, or am I just imagining things and you don't have to write down the reference number on the label at all?
