If you ever saw those iPhone manufacturing factory photos, the engineers and workers were wearing gloves and caps to keep foreign objects and hair and **** entering the iPhone 3G box.
I think everyone should go to China and see for themselves how things are done before stereotypes are made or just keep their mouths shut.
I wouldn't say that Chinese factory workers rubbing **** and coughing on newly manufactured products is really a stereotype, at least not one I'm familiar with.
I was just trying to make the point that checking you phone for germs (like anyone would ever do that) doesn't mean it's new or refurbed.
