I'm using a 3GS that came with 3.1.3 (I assume new bootrom), I'd like to install 4.0 jailbroken. So far I've gotten to the point where I realize I might need 3.1.2, however, it's impossible for me to do so without SHSH, which I don't have because I've never used cydia on this device.
Can I still jailbreak this? Is there a workaround?
