I have an 8g ipt1 with 3.1.2 but I suppose I can downgrade to anything just by dling the .ipsw right? So my question is what do I need to downgrade to to get a working jailbreak? Blackra1n does not work and yes I've tried everything from putting it in C: to switching the USB ports, etc. Hours and hours spent trying to get blackra1n to work. I've also tried redsn0w and some others that don't work either.
