The possible, yet highly unlikely event of a full iPhone 4 recall would cost Apple dearly, according to Tony Sacconaghi of Bernstein Research.
He has issued a report with a US$1.5 billion price tag as his best guess. However, that's not what Sacconaghi believes will happen. Instead, he suspects Apple will relent and issue free Bumper cases to those who want them. With an estimated production cost of $1 each, the cost would drop significantly and frankly hardly disrupt Apple financially.
Earlier this week, several people suggested that a recall is inevitable, while others insist that it's not really a big deal. As I said yesterday, whatever Apple's going to do ought to be done sooner than later. While Apple is silent, consumers are seeing stories like this.
