As above. It seems fine, a bit more responsive from 4.2.1 but that maybe the placebo affect, lol. I did use 4.3.2 firmware with redsnow as I couldn't find my 4.3.3 ipsw file after updating with iTunes but hey, it still worked fine. Go ahead guys. A tethered jailbreak that is working fine. I use sbsetting, bitesms, ect and they all work fine too.
