Newbie question about selling a unlocked phone!

[Ivoryplum]

So I'm currently selling a iPhone 3G and know it's worth more if it's Jailbroken and Unlocked.

I don't want to screw the customer, and want to make sure I did everything properly.

I followed this tutorial to Jailbreak and Unlock it:

Jailbreak and Unlock iOS 4 on iPhone 3G using redsn0w [Guide] | Apple | iThinkDifferent

I couldn't get this repo to work though, and wanted to make sure it wasn't necessary (since I didn't see it on another unlock tutorial):

Repo - http: //apt.saurik.com/cydia-3.7

I have both redsn0w and ultrasn0w downloaded and installed on the phone.

Is this all I need to do to allow the phone to work with any GSM sim card worldwide?

Any help would be appreciated, thanks!
