Same thing happened to the I-Pods that were hacked a while back. The firmware update was designed by Apple to kill the phone....Neat trick....
I can't imagine why buyers of Apple I-phones took it in stride and bought another....
Weird....
More FUD. The 1.1 update for the iPhone bricked the jailbroken iPhones because they were jailbroken by using a security vulnerability. Apple merely fixed the vulnerability. In fact, Apple redesigned the OSX architecture on the iPhone, moving the users to a "standard user" instead of administrator level access. That was a security move, not a move to deliberately "brick" the iPhone's of people who had hacked them.
Apple even explicitly WARNED updaters that if they had hacked the phone and/or installed unauthorized software, they were at risk of the update failing and their iPhones failing to work.
Apple was not responsible for warranty repair on iPhone's that had been used in violation of the EULA... although almost all of the "bricked" iPhones were working within two weeks as the crackers found another method to access them. Now, in a couple of weeks or so, third party software will be available with a legitimate method for installation.
