Starting next week, get your carrier's permission to unlock your phone, or you're a lawbreaker
It's a little-reported fact that, starting Saturday, you need the permission of the carrier who originally sold you your phone to unlock it, or open it up for use on other networks. Unless you can find an already unlocked phone, or convince your carrier that you'll come back from Europe, you swear.
It's a part of the DMCA that was reviewed and changed back in October, and a 90-day window on new phone unlocking is expiring. More at the post.
