I have tried this but not sure I really understand what you mean when you say "If you are using Windows and Internet Explorer, make sure you rename the file back to have an extension of IPSW if it gets renamed with ZIP. This is a fault of Windows and IE. Do NOT extract the ZIP file ". I have downloaded the software twice and when I hold the shift and click restore in itunes, it doesnt see the folder with the firmware in it. What am I doing wrong? I didn't see where it renamed the file with ZIP but it was a zipped folder that it put it in. I downloaded it again and added .ipsw to the file name and itunes saw it then but I got an error when I tried to use it. Please make this clearer for a dummy.
