Hi I just bought a new iPad 16gb 3g iPad and it has firmware 4.2.1. I tried to following instructions in iClarified to restore with the custom 4.2.1, then use redsn0w 0.9.6rc8 to jailbreak but when the process hangs when the iPad screen displays "Downloading Jailbreak Data". It runs about three green blocks then hang and won't continue. Am I doing something wrong? Thanks for any help, really hope to get it jailbroken.
