Yeah, the title pretty much says it.

How can i downgrade from 4.0 to 3.1.x with unlock and jailbreak without the old pc?

I bought the iphone 3GS in a shopping center in thailand. It was imported from usa to thailand and it was still in the plastic thing thats around the box that you get it in. And the guy i bought it from jailbreaked it and unlocked it on 3.1.3.

The iPhone 3GS worked fine and i had no problems with it. Then i tried to upgrade the iphone 3GS to 4.0. But i havent found any unlock or jailbreak for it with that hactivation thingy or whatever its called.

Then i tried to downgrade again to 3.1.3 and i get this error 1015 or something like that.(<-- this was on my pc <--). I dont have that pc anymore(dont ask me why :p) I tried something called iRecBoot but it didnt work.

After that was on my moms pc and i tried to uninstall itunes(9.2) and install 9.0.3 version. This was for 3.1.2(iphone). I deleted the itunes library thingy and it worked. But when i tried to restore it to 3.1.2 i got this error: 3194.

I dont know what to do and i have tried lots of guides without success.

PS: i had the cydia host thingy when i tried to restore it to 3.1.2

And when i have it on 4.0 firmware it says its the wrong simcard and i can only go to emergency call on it...
