As of Saturday, unlocking a cellphone is against US law.
The process, which allows you to use your handset with a network other than the one you bought it from, has just become illegal again as part of the Digital Millennium Copyright Act (DMCA).
Unlocking was formerly allowed under an exemption to the act, ABC News explains, but in October 2012 the the US Copyright Office and Library of Congress decided not to renew the clause and it expired on Jan. 26.
Now, you must obtain your carrier’s permission to unlock your phone or face a potential fine of up to $2,500. Anyone found unlocking handsets for profit could be forced to pay up to $500,000 and may even go to jail, according to ABC — via redwolf.newsvine.com
