ofcourse it's illegal because jailbreaking is illegal and anyways even if u jailbreak it the police isn't gonna come after u for that
i just know one i think: blackra1n
Blackra1n is available at the official website (in the related links section)
"blackra1n is a program that jailbreaks versions 3.1, 3.1.1 and 3.1.2 " So if you have any of the listed iOS firmwares then blackra1n will work for you.
no not with blackra1n
yes
After installing blackra1n it will say that because it accomplishes the jailbreak on the fly which means it patches up the firmware in recovery mode. if you have ipod touch 3g then you have to run it twice (blackra1n). the ipod touch 3g is a tethered jailbreak by the way which means that when you turn it off or to reboot it you have to run blackra1n to get to restart.
you need to jailbreak it. It is not illegal, but somethings in cydia are. You can jailbreak it using spirit or blackra1n
Yes, when you finish installing it, it has a bar on the bottom that says, "Uninstall Blackra1n". Just click that and your iTouch/Phone is completely restored.
blackra1n
blackra1n, absinthe
no but there are other ways...
Spirit, blackra1n, or redsn0w
