Where Does Seas0npass store the ISPW files on a Mac?

I’ve been troubleshooting a problem with XBMC all day and I believe I have a botched flash.

I want to start over fresh with Seas0nPass downloading a fresh new ISPW from Apple and patching it.  I deleted the modified one in my home folder, and then I went into ~/Library/iTunes and deleted the one there.  But when I start Seas0nPass and click to create one, it starts unzipping something right away (doesn’t download a new one).  What is this file it’s unzipping and where is it?

I found it.  ~/Documents/Tether.  How strange.
