This is what Sn0wbreeze does, but it gives me that error, so it somewhat leads me to say the Apple now verifies the restore and checks for a jailbreak.
Update: I just used TinyUmbrella and I really have no clue what to do. I have PC not a Mac so IDK how to get it for Windows, many people are saying Sn0wbreeze is it, which is what I used. But now, when I used TinyUmbrella, I got a error code of 21, not 1600. So it did something, but IDK what. I'm new this this type of jailbreaking, otherwise I usually use greenp0ison, but now these new updates have ma all confused. Lol. Please help...
