I'm getting an iPod Touch for Christmas, and I need to know what kind can currently be jailbroken. I know the 1st gen can be jailbroken, but what OFW does it need to be? Can it be downgraded? Can the 2nd gen be jailbroken yet? What OFW does it need to be? Can it be downgraded? Please give me details, because I'm trying to find out which one I need. Thanks P.S. How can I download apps for free?
