So I upgraded my 3GS to 4.2.1 in hopes to jailbreak. I've been reading everywhere that since November, the old bootrom 3GS's can boot untethered. Well, I've run redsn0w a handful of times and it's still forcing me to be tethered. (stuck on Apple logo) Is there something special that I need to do that I'm just skipping over? In the popup menu, I told redsn0w it's an old bootrom, so it should be good. Maybe point it to certain firmware? I would use PwnageTool, but I need it hactivated so that won't work at the moment. Thanks!
