"Based on retail prices of iPhone cases, supplying one to all three million customers could cost Apple about $180m (£118m)."
You really don't think that the economy of scale will kick in with an order of 3,000,0000?
The reporting on the whole iPhone 4G has been riddled with stuff like this since the story of poor reception first broke. They are still reporting the signal loss problem will mainly effect left handed users... Clearly the reporters who keep cut and pasting this have never used an iPhone or didn't give a moments thought to how one interacts with the iPhone.
Of course the questions I want asking never get asked by journalists... Like for instance;
"Are you going to keep churning out phones off the production line that have this fault?"
"If so, is the workaround just keep supplying covers?"
"How the hell did this get past product testing?"
"Did Jason Chen pick up on the problem while he had that one that went missing?"
"Could we interview Ruben Caballero?"
