Seems kind of ho-hum in that it reads a lot like AT&T's current policy for unlocking. Perhaps other carriers are different, and hence the reason this would be a big deal. But read it, it's not saying the carriers would have to unlock two days into a two year contract. No, the contract must be fulfilled or the ETF paid. They wouldn't have to unlock just because you say so.

As always, if you want an unlocked phone, then buy an unlocked phone. Plenty of places sell them.
