i am getting a 64GB iPod Touch 4G soon. i want to have my hacked firmware ready to go, how can i prepare the jailbroken firmware so it's ready to go. i can't use the plug iPod in and use GreenPoisi0n method, as i don't have my iPod yet.
there is an untethered jailbreak but it's strictly for mac users. plus 4.3 is coming out soon (rumored to be released on the 14th, but we'll see about that). google it and you'll see what im talking about.
Greenpois0n is really the only jailbreaking software that is available for Mac, Windows 7, and Linux. so try looking up and downloading greenpois0n. Im using it on my iPod Touch 4G(4.2.1 [8C148]) and it works perfectly.
