Is there no untethered JB for Iphone 3GS on iOS 4.3.5? Tried Redsnow but its a tethered JB.

Guys,

Just tried to jailbreak my 3GS iOS 4.3.5 with Redsnow but failed. Its now just stuck at Apple logo. Now trying to restore and keep coming with the first message:
"iTunes has detected an Iphone in recovery mode. You must restore this iPhone before it can be used with iTunes."

In iTunes, my iPhone only displays
Capacity: n/a
Software version: n/a
Serial number: n/a

I then proceeded to hold down shift and click on Restore. I first proceeded to restore using the 4.3.5 restore IPSW on iTunes. iTunes dispalys:
"iTunes will erase and restore your phone to iOS 4.3.5 and will verify the restore with Apple."

But after software extraction, Itunes unable to restore and displays the message:
"The iPhone "iPhone" could not be restored. An unknown error has occurred [3194]"

I then repeat the process with a 5.0.0 restore IPSW but same thing happens.

Im connected to the internet during the whole process and my iTunes is the latest version. Any remedy before I officially declare my 3GS is the most expensive paperweight in the house? Also maybe go buy Magnum on 3194.

Bumping up for assistance
