Have you ever wanted to jailbreak your iPhone, iPad, or iPod Touch? Lots of advanced users do. But it has been in a legal gray area for a while because of contradicting clauses of the DMCA. Every 3 years, a rulemaking session allows exceptions to be made to the DMCA. This year, thanks to the EFF’s lobbying, the rules now recognize jailbreaking as a legal action. You still can’t use pirated apps of course, but now you can use t-mobile on your iphone, or run Flash player on your iPad.
That doesn’t mean its without risk though: it still voids your warranty, and opens up a hole in the OS for hackers. You need to change the SSH password.
