Look for foobar.ipsw.zip in your trash. Move it elsewhere. Rename it to foobar.ipsw

You have to remove the .zip from the end of the file, and it will work just fine.

no file named foobar.ipsw.zip anywhere at all on my mac

It's not really called that, I think he was just filling in something because he doesn't know the exact file name. Just drag it out of the trash and remove the .zip from the file name, and iTunes will recognize it correctly.

use a different browser to download the file. Safari doesn't like downloading the firmware files correctly, but firefox grabs them fine...
