Every iPhone 4 can be returned for a 100% refund.
So customers have recourse.
This recall business is nonsense. It's not like a car which poses a danger to the owners and others.
We don't know what percentage of iPhone 4s have been returned but if it was any significant percentage, then we'd know about it.
So for the vast majority of those who bought the product, there isn't a problem or if they think there is, they have recourse.
Apple didn't get where they are by listening to these PR consultants.
