I've read comments all over the internet about what Apple said and I think you have to understand there is a tinge of schadenfreude going on in quite a bit of them.There will be, always, a way to hack the iPhone moving forward. Only when the hardware is changed will the hacking get more difficult again. You will see, within a matter of days if not hours, that the unlock/activation process now available will be restored with the newest software update.
The Dev team has, with each passing day, learned more about the internals of the Phone and the way in which the system operates. Any changes in software updates can be analyzed and compared, and its modifications found easily.
Apple is certainly obliged in contract with AT&T to make a 'vocal' effort to maintain their partnership through exclusivity protection actions.
But keep in mind everyone that unlocking a phone is NOT illegal in the U.S., or Canada for the matter. If it can be proven that the software based modifications do not damage hardware or hardware functionality, and that the phone's legitimate use has been thwarted by Apple Inc., lawsuits will eventually be filed and Apple will lose.
