Fix recovery with Tinyambrella, restore with FW 4.1.
with redsn0w, tick cydia and instal ipad baseband.
Then instal Ultrasn0w.

How about we do this step by step...
1.use redsn0w 0.9.6 beta6, choose ipsw 4.1,select enter pwnd dfu mode.
2.let redsn0w complete process finish open itunes,select custom firmware 4.1
3.itunes restores successfully...open redsn0w again and only install cydia.update cydia complete..

should have a fully jailbroken 3Gs...factory unlocked should work fine.
