Well looks like Apple isn't quite as smart at they thought. The new iPhones and iPods can be jailbroken. Yes Apple did change out the bootrom to a new one but you can still hack it. You now need to do a few extra steps and it requires tethering it to a computer to start up. You can read more about it here:

McDonald explained that current tools will still work with the latest batch of iPhone 3GS units. The “24kpwn” exploit used to help jailbreak previous iPhones and iPod Touch devices only made it easier to boot up the hacked devices.
The newly shipping iPhone 3GS’s bootrom interferes with 24kpwn, but that will only make the handset difficult to start up after it shuts down. Booting up will require being “tethered” to a computer. That means if you shut down a jailbroken iPhone 3GS, or if it runs out of power, you can only turn it back on by plugging it into a computer.
In short, changing the bootrom makes owning a jailbroken iPhone even more of a hassle than it already is. However, McDonald said the Dev-Team will just have to find a new exploit to enable untethered booting once again.
Well I'm hoping that they find a new exploit and a easier one - I'm sure they will. 

I did find out that my son's ipod is one that has to be tethered it it shuts down. For now were not going to jailbreak his. I know there is a Beta jealbreak for the newer ones but I'll hold off till its out of beta.
How do I know its a tethered one for sure? His buddy bought one the day after he did and he did jailbreak his and is not tethering it.

This is just like the jailbreak for the newest Touch that Geohot released. If the battery dies or the phone needs a hard reset you have to plug it into a computer to boot it. If I remember correctly with Geohot you had to rerun Blackra1n to reboot. I have to say as often as I was doing hard resets with 3.1 I wouldn't jailbreak that firmware. With 3.1.2 I've only done elective hard resets when I stupidly created an issue with my Photo app.
