You will need ..
1-QuickPwnRC3 download from here ( iphone-hacks.com/downloads/file/138
2-2G Ipsw 2.0.2
3-iTunes 8.2
These steps is to put the iPhone in a mode to allow iTunes to restore to lowers ipsw, if you do DFU the normal way iTunes will give all possibele errors such as 1600, 1601, 20 etc.
Now follow my steps..
A-Open QuickpwnRC3 and follw the steps and select 2.0.2 IPSW and when the screen turn to White color , unplug the USB ( Screen will remians White color).
B-Disconnect QuickpwnRc3
C-Reconnect iPhone
D-iTunes will discover iphone in Recover mode.
E-Shift+Restore to 2.2.1 (with Quickpwn 2.2.5 – http://daniel14.com/QuickPwn-225-2.zip)

Itunes continues the restore process without any erorr

100% works on booth 2G-3G
