hey, if you can find a 3.2.2 ipsw file on the interwebs you can control-click the "restore" button in iTunes and it will ask you to navigate to a custom firmware file (that ipsw) and you can restore that way
That is what I have, but i can't find a way to browse for it, anyone?????
On windows hold down the shift key then click restore and iTunes will let you browse for it. A Mac is like the command key or something.
