Though not directly hosting any software, BluWiki is home to numerous sets of documentation that help people tinker with their iPhone, including ways to get around the protections Apple has built into the phone. Documentation of these holes is apparently enough to get Apple in an uproar, which resulted in BluWiki being threatened with legal action. Rather than caving in to pressure, though, BluWiki has instead gone on the offensive and is ready to take Apple to court, claiming that the documentation in no way violates the DMCA.
Apple is no stranger to the legal system, and it seems that IP lawsuits generally favor them. Not always, however, and given that BluWiki is a noncommercial site and doesn't run ads they could stand a chance here. BluWiki’s operators say they are suing Apple in hopes of protecting the free speech of their users and getting a declaratory judgment that posting information does not violate the DMCA.
