Ive been researching how to jailbreak my iphone recently. Upon getting 4.0, i realised that its simply not that great. I really really want to jailbreak but i have never jailbroken before thus i have no blobs. Is it possible for me to downgrade from 4.0 to 3.1.3 and then jailbreak. i have the new bootrom. Im frustrated to no end. any and all help would be appreciated. i fear the worst.
