I want to jailbreak my IPAD 4.2.1. 8C...MB model.....i saw a few videos on Youtube on Spirit and seems rather easy...can i Downgrade and JB it that way or do you recommend that I JB it with redsn0w and using DEV TEAM website? Im REALLY nervous im going to mess up my IPAD and dont want to do that. Ive never jailbroken anything before !!!
