iPhone unlocked

I heard this story on the radio this morning and also just saw it online. The iPhone has been unlocked, meaning you could buy one and use it with whatever carrier you choose, not just AT&T, and not just in the US. You wonder if Apple will try to stop it through software updates or legal action, or both. I don't have an iPhone and don't plan to get one due to my lack of interest in phones in general, but I might be more inclined to consider one if I didn't have to continue to go with AT&T. My contract expires next month and I look forward to getting poor service from some other carrier for a couple of years.
