To restore any .ipsw file to a device using iTunes, just put the device into Recovery Mode, then hold down the Option key when you click the “Restore” button in iTunes.

iTunes will then present a standard File Open dialog, where you can navigate to and select the .ipsw file.  iTunes will then restore that file to the device, instead of trying to look for it over the Internet (where it doesn’t exist, which is the issue here).
