I keep trying to jailbreak my ipod with redsn0w but each time i click browse when i open redsn0w, to look for the IPSW for my firmware (4.2.1) I can never find anything. So what's another method to jailbreak an iPod Touch? I can't use jailbreakme.com because the jailbreak for 4.2.1 isnt out yet and i want to jailbreak now. Any help?
