I tried it on my ipod touch running iOS 4.0, it works! They used pdf vulnerability to do this. Those pdf’s can be accessed from here http://www.jailbreakme.com/_/

If I remember how the previous jailbreaks work, you need do modify both the phone-side OS as well as the PDA-side OS. This hack seems to initially just involve the PDA side OS as they state that you still need an additional app to unlock it. 

Anyway, I would think that the modification to the OS can be detected, if not just because you can access the alternative App Stores.

 

Cheers, Morton
