Hello, I got an iPod Touch 8 GB with firmware version 2.2.1 (5H11a) and I want to jailbreak it but I am having issues with redsn0w 0.7. I got the IPSW I think which is the right one but it will not recognize it. How can I jailbreak my ipod for free and properly? I want to be able to make themes for the iPod. I apologies but I am very new to all of this.
