  3. Ur doing god's work! I hope u kno that!!! I nearly pissed myself wen I saw this video n the one for Mac. I have been following ur videos for quite some time now. N I just want to thank u from the bottom of my heart! I had many problems with my tethered jailbreak n u solved all my problems! As soon as I get to a pc I'll try this jailbreak n comment u bak on how it's working for me. Thanks again!!!


  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!
