Okay, I'm no newbie but I am stumped on this. Just got a new iPad 1. It came loaded with 3.2.2 (blow out pricing at Verizon). From all my reading, I can't jb this firm version. So, I dl'd the iPad 1,1 4.2.1.ipsw file so I could utilize the Greenp0is0n app (which, I gather 'used to' work on 3.2.2 but now requires 4.2.1). I shift-click (PC) to install that and Apple won't let me (natch, cuz it isn't 4.3.1). Since this is new, with unbreakable current firmware, I have no shsh blobs I can reference saved. So, changing the hostfile won't help me as there is nothing a cydia I can retrieve. Question, in short, what do I need to do to jb this?
