In need of help

Hi, I'm not sure if this is the right place to put this thread, but I'm in need of help.

I recently tried to downgrade my Iphone 4 from version 4.3.5 to 4.3.3 and in doing so edited my host file.

Now my entire windows\system32\etc folder is missing, including my host file. Any help would be greatly appreciated. Thank you

I'm confused as to how downgrading your iPhone would have anything to do with a host file, but I'm guessing if you edited the host file, you had to edit the properties of the folder. Make sure you don't have the view set to hide certain folders, and check your recycle in, too, just in case.
