My iPod Nano (3rd Gen, I think) was stolen while on holidays. My travel insurance company requires proof of purchase. I don't have the receipt or the original box (I had these recycled long ago!). However, I'm sure there must be evidence on my MBP somewhere that it's been in my possession. In particular, I mean that I registered my iPod with my MBP some time ago. Is it possible to find/access a file somewhere which I could print out proving that I did, indeed, own this iPod?
