The resolution does not tell me the location to place the ipsw file nor does it tell me where to download it from. Your directions are too ambiguous!
With iTunes when I select the "Check for Update" button I get a pop-up window that wants me to enter the directory path of the .ipsw. I have no idea where the .ipsw is located. I though iTunes knew where to get if from?
iPhone 4, iOS 4.2
