no it is not illegal. they have now confirmed that it is legal. but it can mess up your ipod for good.
It is up to you. No matter what you have on your ipod will become messed up when Jailbreaking...
As of today (November 24th, 2010), jailbreaking an iPod Touch is not illegal. Is it 100% safe? No.
Jailbreaking an iPod could either be a success or a failure (meaning your iPod could break). It's your decision, but a risky one.
I am pretty sure it does not, as it only uses the hard drive, it does not mess with the MotherBoard, as far as I have seen.
I think that many people are finding the most jailbreaking software for their ipod.
Yes, jailbreaking does void the warranty.
i would say no because there is too much of a risk that your iPod will get messed up. if it gets messed up you would probably have to buy a new iPod.
Yes
It is illegal.
