It's not clear if any companies are actively opposing the foundation's attempts to legalize jailbreaking this time around, but device manufacturers have been busy trying to prevent jailbreaking in recent months.
Rooting out jailbreaks
It took hackers about 10 months, an unusually long time, of hard work to create a usable jailbreak tool for iOS devices equipped with Apple's dual-core A5 processor, which include the iPad 2 and iPhone 4S. Asus's recently released Transformer Prime Android tablet shipped with a locked bootloader, making it harder to root the device. A bootloader is a piece of code that starts up a device's operating system. Asus ultimately relented to user demands and plans to release an unlock tool for the Transformer Prime bootloader in February. But Asus also said that unlocking your device's bootloader voids your warranty.
Sony has also been working to stop people from hacking into the PlayStation 3. In early 2011, hacker George Hotz along with several colleagues posted PS3 jailbreak tools online allowing anyone to open up their gaming consoles to unapproved software. Sony hit back demanding the hackers remove the software and then suing Hotz over the jailbreak. In the end, Hotz settled with Sony out of court.
The Electronic Frontier Foundation in December called on Apple, Sony, and other manufacturers to stop opposing jailbreaking.
