Please help! 3GS unlocking issue

[Inwood]

I successfully jailbroke my 3GS on 3.1.3 with Spirit. I went into Cydia to add the source repo666.ultrasn0w.com, but every time I do I get the following error message:

Did not find repository
The indicated repository could not be found. This is because you are trying to add a legacy Installer repository. Also, this interface is only capable of working with exact repository URLs...

Is there a way to work around this issue so that I can unlock my iPhone?

Thanks in advance for the help.

Oh I also forgot to mention the following specs of my phone:

Firmware 3.1.3
Baseband: 5.12.01
Bootloader 6.4
Bootrom 359.3

make sure you typed the repository correctly http://repo666.ultrasn0w.com/ I always use to forget the last / on alot of my sources also the o in ultrasnow is really a zero=0 not o
