Some of the iPods get new cases when they're refurbed so they look like new. Is this true with the iPhone 3G as well?

Mine needs to be replaced (dust under glass) and I'm unsure if they'll replace it with a new unit or a refurb, but I'm not too thrilled about the refurb if it's already beaten up. Mine has been in a case for the last four months and is only faulty due to a manufacturing error.
