No doubt this is not the sort of news Apple would like to see right now. They're already defending themselves in a dispute with the Electronic Frontier Foundation over iPhone jailbreaking.
The EFF recently filed a request with the Library of Congress asking for jailbreaking to be exempt from the DMCA. They argue that it's essential for giving consumers an option to use whatever software they want on their phones, rather than being limited to whatever Apple allows.
Apple's rebuttal that the iTunes App Store provides all the choice necessary seems somewhat hollow in light of decisions like this one.
