any help with Centennial myBlue Web settings?

[n1toad]

I still have the myBlue Web unlimited on Centennial Wireless ('joined' ATT) and it works great on my Nokia smartphones using these settings but I get "Web page not available" when I use it in my N1.
Does anyone have this working or know the values needed for the N1 (ATT version) below? THANKS!
