Apple ipod

or jailbreak iPhone 3G 4.0 Downgrade 13/05/2005 Baceband?

I am a 3G FW 4.0. It came with FW 3.1.3 and I did a jailbreak mind. The GPS does not work anymore so I did a restore of the phone. He stopped halfway and stops. I could not make it work. He was caught in the Apple logo and restorations no. work with iTunes. I had the day up 4.0 to work, but now I can not jailbreak. I searched the Internet and all I could find some programs and closing Bata. I thank my best bet would be to degrade and I how to look, but nothing works. I thank I'm doing something wrong. So what I ask is that if someone could aa step to step on how to downgrade from 4.0 to 3.1.3. If you talk to me e-mail to Thanks hooeruncle@yahoo.com
