Eh, sure - the iPhone 4 has many other flaws, but I think that the 'Grip of death' is the funniest of all: for once, Apple tried to use a different antenna design other than the design they copied from Nokia, and it ended up as a miserable fail. I know you know deep down that such a hardware design flaw cannot be resolved by a mere software update - therefore I don't see any reason why should anyone "use another attack vector towards iphone 4" - as this one is quite enough
