Hey so I bought my friends old I phone 3gs. It is a 16gb iphone 3gs on 4.3.2 firmware. The sleep button is broken so I had to use pliers to put it into dfu. The problem is that every single jailbreak I have tried has failed. No matter what I do. I used redsn0w, but when I tried installing the custom firmware I gpt "error 21." So I looked on some forums and got a little further but then got "error 1601." Tried to fix it but nothing worked. I tried blackra1n, but it got stuck on "running." I tried limera1n but it also got stuck on running. Even redsn0w got stuck. I don't know what is wrong. Someone please help! I am running on a pc netbook by the way, because my mac mini is getting repaired.
