As a Best Buy employee, allow me to share some insight: Whenever you purchase something there, the transaction is stored in the computer system and linked to your CC # and name. We regularly look back years in the past to get receipts for people so they have proof of warranty/etc. This is strange, however, as I've never heard of us mailing out firmware updates...

It's possible that it could be impregnated with some sort of resin, making it more of a carbon fiber, just a ton stronger .
