Success! I restored to 1.1.4 and my wifi was back , then I just upgraded to my customized 2.0.2 ipsw, I'm having some signal issues but the wifi and everything else is right... and one more thing, but -I think- this is a genral 2.x issue, the music disappears, you have to sync both, apps and music AT THE SAME TIME, otherwise your music won't last or won't even sync to your phone.
