Hey everyone, So I received my iP4 with firmware 4.0.2 installed by default. Then, 4.1 was released so I found no harm in upgrading because I wouldn't lose a jailbreak or unlock or anything of the like. Anyway, not having a JB is REALLY annoying me. Is there any way to downgrade to 4.0.1. Obviously I have no SHSHs, so I really am doubting whether this can actually be done. Thanks!
