Hi guys. Just got a new Ipad 64Gig (Wifi) only yesterday. Running OS 4.2.1 I downloaded and ran GreenPois0n rc5. It appears that the DFU works and the green progress bar fills up, but the message "jailbreak failed" comes up. I am running Windows XP on my computer and downloaded the appropriate Windows file from the GreenPois0n file. I'm dying to get this thing jailbroken! Does anyone have any suggestions? Thanks!
