Got it working.

For anyone else struggling with 1600 error message from iTunes,
you can get past that with winpwn 2.5 and iPhone1,2_2.0.2_5C1_Restore.ipsw.

Run winpwn until it crashes with a white screen.
Run iTunes - it sees this as a jailbroken iPhone in DFU mode, and will restore it.

Thanks.

I have been getting this for hours.. updated from 2.2.1 to 3.0 on a 2g iphone on windows and it's showing me the emergency screen , can't even get it to downgrade or do anything for that matter.. any advice please?
 
the win 2.5 instructions to get to dfu with the white screen worked great. Wish I saw this earlier would of saved me 4 hours of problems. :)
