Im so useless at all this. So, I jailbroke my iPad2 on 5.1.1 ages ago. Its just causing me so much hassle that I want to go back to normal. I want to restore it to its factory settings. (everything is backed up to iCloud) I hear about these blobs but dont know what that means. Also, if it helps, Im using iTunes 10.6. Am using an old MacBook and am unable to upgrade. Any help please!!
