wellington map writes "A mobile phone company is arguing that companies that unlock their handsets violate the DMCA. They argue that the software on the phone is a copyrighted work, and the unlocker is breaking DRM in a way that violates the statutory prohibition on circumvention. A similar claim by Lexmark, which tried to apply it to people who refilled printer cartridges, has recently been rejected by the courts." From the Wired article: "The financial motive behind this claim is obvious. Companies have been using the razor blade business model to guarantee a steady stream of revenue ever since, well, the razor blade. Cell phone companies sell you a phone at a discount, and then make up the difference by requiring you to sign a multi-year contract promising to pay monthly fees for mobile phone service or to fork over a hefty termination penalty if you break the deal. But many customers, particularly those who travel internationally, want more choice."
