So long story short, Apple is sending me a unibody Macbook Pro due to many problems... that is, after I mail them my Penryn one. I'm not exactly sure what to do though. Do I have to pack in all the power adapters and return it in the original packaging or can I just find a random box and bubble wrap it and send it off? Also, Apple sent me an email with some UPS instructions which aren't clear at all. They tell me to print out this sheet of paper which tells me to fold at a line. But half the paper is blank so I don't know what folding it will do. Also, that piece of paper is full of instructions and it doesn't tell me to attach it to the box or anything. I feel so stupid. Who's had experience with this process before?
