3GS Update/ iTunes Probs

[Rockiii]

Hey Guys, following Problem with my 3GS.

I?m on iOS 5.1 now, and my iTunes isn?t willed to get an restore confirmed by Apple (Error 3194)

I?m wondering where i can find a solution to update it to 6.1.2 without iTunes, but didn?t find a way yet.
If it?s not working, i want to make an UNtethered Jailbreak, now the iOS 5.1 is tethered with Redsn0w...

My Firmware is: 05.16.05 Serial: 8594MXK3NQ

Hope somebody can give me a clue in one of these issues.

Regards

Solved.

The 6.1.2 wasn't longer approved by apple, so i couldn't update.

Now i'm on 6.1.3

Yeah it's working but you lost your jailbreak.
