    is it possible to downgrade an iPhone 4 that came with 4.2.1 stock to 4.1? I was thinking if it's possible to using redsn0w to put the phone it pwnd DFU mode, then installing a custom 4.1 ispw.

    I haven't tried it, but I was thinking it might work. My co worker got a phone recently and it came with 4.2.1
