hmmmm....ok...might have to mess around with iTunes.
Completely uninstall iTunes...trash them..even the execution file.
Go to Apple site, download the fresh new iTunes app...and reinstall it.

Btw, if you already have 2.0.2 on the phone...then all you need to do is download the actual 2.0.2 fw for first gen...and use this to make your custom fw...then restore your phone with the custom fw that you just built.
