robes1, you need to chill out and get down from your moral high horse! All the outrage??!!
How do you know that they didn't buy an iphone 4s, uninstall Siri, and then install it to the iphone 4?
Jailbreaking allows you to install whatever software you want, not just what Apple (big brother) approves. So essentially, Windows is "jailbroken" too, because I can install whatever software I want, including stolen/pirated software.
Imagine if Microsoft decided to lock down Windows so that you could only install software that they approve and they sold to you. Software pirating has always existed and will always exist. Jailbreaking has nothing to do with it.
I got an idea, if you really want to put an end to pirating, let's make a law against all computers, and cell phones. That way, there won't be any software to pirate.
Relax about Siri, I think Apple is big enough to know how to deal with the server loads once the novelty wears off after a few months. Then Iphone 5 will come out, and guess what, it will have Siri too, and so will every iphone, so eventually the server loads will go way up.
