Have you ever wanted to unlock your AT&T locked iPhone and use it on T-Mobile? Until yesterday, that was illegal. Now, there's no stopping for US citizens who want to do that.
The White House and Senator Patrick Leahy have announced that president Barack Obama has agreed to sign what is called "Unlocking Consumer Choice Wireless Competition Act."
This bill only applies to US citizens and to phones purchased in the United States, but will surely open the flood gates for phones to be sent overseas. This is not the first time unlocking was made legal. Back in 2012, the Digital Millennium Copyright Act did a similar thing, but the bill was not renewed in 2013.
The new bill is not permanent, but it can be under debate again in the future, and the arguments of the copyright fighters may be accepted. To put it another way, nobody can tell you it is illegal to unlock your iPhone now, so make sure to do it as soon as you can. The bill guarantees you can do whatever you were doing back in 2012. That means, anyone in the US has the right to modify the software in order to get their phones unlocked.
