  4. Well, truth be told I did an untethered jailbreak with greenpois0n and then installed Cydia with redsn0w, and it works fine right now, but I was hearing that once the server traffic died down the problems with greenpois0n's installer app began clearing up. I guess thats not the case 😛

  5. @Hayaserforeveer Its not that bad really, I have a jailbroken iPod 3g on 4.2.1, the only problem was that the greenpois0n servers were down for a while. Once they got that fixed everything worked!
