I have a iphone 3gs with a ipad baseband on 4.2.1. When the 4.3.1 jailbreak came out i created a custom image on snowbreeze and put it in pwned dfu and tried to shift+ restore it was all good until it got about 95%. The iphone turned off and got stuck in the recovery loop and itunes said 1015 error. I tried to fix it with ireb but its still stuck. I am back on 4.2.1 but is ther a way to get on 4.3.1.
