In what is pretty much a landmark decision for digital copyright, the DMCA has been modified so that things like jailbreaking your iPhone and copying DVDs for educational purposes are now legal. So go ahead, install your Cydia Apps, get tethering, install SNES emulators — it’s a free country, man. Here’s the exact line in the revised legalese:
(2) Computer programs that enable wireless telephone handsets to execute software applications, where circumvention is accomplished for the sole purpose of enabling interoperability of such applications, when they have been lawfully obtained, with computer programs on the telephone handset.
(3) Computer programs, in the form of firmware or software, that enable used wireless telephone handsets to connect to a wireless telecommunications network, when circumvention is initiated by the owner of the copy of the computer program solely in order to connect to a wireless telecommunications network and access to the network is authorized by the operator of the network.
