Can you help? Sorry, I’m a newbie to this whole jailbreaking thing. I downloaded the iOS 4.2.2 from the site, but it only appears as a folder on my desktop. I can’t find any file in it with an .ipsw format, and nothing that Snowbreeze will recognize as an acceptable file. Same if I unzip items in that folder. Thanks
just rename the extension from .zip to .ipsw
