Proper jailbreak procedure?

[jsh]

A couple months after the 3GS, came out, I moved to Canada from the US, and I bought a 3GS here. I'm finally getting around to sell my US 3GS -- it's on the original 3.0 firmware and baseband, and I do not have a SHSH (I honestly haven't even used the phone in the past 11 months.) With this in mind, what is the recommended procedure for unlocking, so I can prepare the phone for sale?

Thanks!

Sorry, can't edit the title. I'm looking to unlock primarily (if unlock means I must jailbreak too, that's fine.)

Redsnow to jailbreak, then Ultrasn0w to unlock (baseband should be 4.26.xx)
