I'm still loving my iPhone 3G, but over the weekend I spotted a problem with it. A small bit of dirt, about the size of a grain of sand, has appeared inside the screen.

It is pretty much in the middle of the screen, so is fairly annoying.

I guess I need to make a trip to an Apple store. Does anyone know if they are likely to fix/replace it or just say "tough" ? I'd certainly count it as a manufacturing defect, there shouldn't be any dirt in there get dislodged.

If they do replace it, presumably that will be with a refurb ?
