Hey guys, I just received an email last night from Apple thanking me for registering my new ibook. They also say to put my receipt in a safe place because it will be needed if I should ever have to use my warrenty; however, I realized that I never got a receipt in the box. I'm the kind of person who keeps all kinds of papers, especially when I order something, so before throwing out the brown shipping box, I made sure there wasn't any papers or anything in it. I still have the box from apple but no receipt. I have all the emails I got from apple when I ordered my ibook and on one, it says proof of purchase. Can this still be used as a receipt if something should happen to my ibook, hopefully I won't need it.
