Hacker breaks link between iTunes and the iPod - Times Online:
A notorious Norwegian hacker known as DVD Jon is preparing for another run-in with the music industry after he released software that lets iPod owners copy music and videos bought from iTunes and play it on other devices.
The program allows people to drag and drop songs from iTunes into a folder on their desktop, which in turn copies the files to other devices such as mobile phones and games consoles via the web.
In doing so, the software breaks the copy protection - known as 'digital rights management' or DRM - that is built into all music that is bought from iTunes. Music bought from iTunes can be played only on the iPod.
