iPhone 3GS with 4.0.2 iOS jailbreak/unlock

[jjsto]

So, I have spent the last day or so trying to unlock my iphone 3gs as well.

It is running 4.0.2 and 05.13.04. Looks like the jailbreak is easy to do, but I still havent figured out how to do the unlock. Does anyone know if it can be done? I also contemplated downgrading to the 4.0.0, but that looks a little risky based on the production date of the phone...

So, if anyone knows how to do the unlock on this, could you send me a pm, or perhaps a link?

thanks

Once an iPhone is jailbroken, the unlock is very easy. Go to the newly installed Cydia app and search for "ultrasn0w". Install this package, and Bob's your uncle.
