You may remember that last year, the DMCA exemption on unlocking phones. Well it went into effect this past Saturday. So, unlocking your phone will be officially illegal.
phones without the express consent of the carrier who locked them
became illegal thanks to edits to DMCA exemptions back in October, but
it's only now that the 90-day grace period is running out. Locked phones
purchased in the 90 days after the ruling are still game to be
unlocked, but from here on out, for an unlocked phone to be legitimate,
it'll have to have been bought that way or come with a permission slip
from your carrier.
Customers looking to root or jailbreak their smartphones can rest easy. Those options have not been made illegal.
