This EFF article on the state of DMCA and cell phone unlocking does not mention any case law validating the idea that unlocking is actually a violation: https://www.eff.org/is-it-illegal-to-unlock-a-phone https://www.eff.org/is-it-illegal-to-unlock-a-phone It does cite case law that points in the direction that the DMCA is only triggered when the lock protects a creative work, which cell phone access may not be. Considering how carefully the EFF tracks these things, if there was case law supporting the carriers' (and possibly executive branch's) position, they would mention it.
