What is happening to the iPhone 4?

Apple has just launched their most successful product in their history but successful product doesn't necessarily mean successful product launch. We all have heard about the reception issue of the new iPhone 4 reported by various media. I myself is also a bit worried 'cos I'm definitely going to get one for myself as soon as it's available in Hong Kong. I'm worried if that issue is really a hardware problem 'cos if so, that can't be fixed easily even if Apple releases whatever upgrade of their new iOS. But funny enough, I've already convinced myself to go for it no matter what!

Apple releases a statement to all iPhone 4 users explaining what is happening. They found that the hardware is actually ok. It's just that their formula to calculate signal strength is wrong. Is it really so? Anyway, I don't care.
