So, people are now going to use a security vulnerabilty to "jailbreak" their iPhones only a few weeks after Apple squashed the previous method for doing so? How long will it be before Apple plugs this hole? And your iPhone is an iBrick? Then you'll complain, threaten to sue, raise holy hell in the forums, etc.
I'm generally in favor of the user being able to do what he wishes with the product he has purchased. You paid for it. It's your choice. Apple has made it very clear that they don't want third party development happening for the iPhone (outside the Safari environment) right now. So while it's your choice to apply these hacks to the phone, I'm pretty sick of the whining that goes along with Apple firmware updates.
And now we have class-action lawsuits? It's absurd. No one is suing car companies over the inability to install Tetris on the built-in computer. Apple doesn't *owe* the user anything beyond what has been sold. Apple views the iPhone as a CE device, not a computer, and therefore doesn't want you messing around with it. So, stop whining when you screw something up and take responsibility for your own actions!
I love my iPhone and, quite frankly, haven't seen a single third party app that justifies "jailbreaking" my phone. Furthermore, since I know that Apple is never going to embrace the hackers who are hacking the phone or the hacked phones themselves, why jailbreak in the first place? The value added is marginal at best and you risk turning your phone into a $400 paperweight. Sorry, I just don't get it.
So please, if you apply these hacks and something goes wrong or Apple plugs the hack in the next firmware update, do us all a favor and stop whining about it!!! And no stupid lawsuits. There are enough of those already.
