You know what's weird?
I distinctly remember seeing a post by EIPI that showed the Wind 3G network displaying on his N900, when he went to Settings->Phone->Network Selection->Manual

But now I can't find that post! Strange.

Anyway, my N900 finds no Wind network here in Vancouver. So that suggests Toronto only? Any other Canadian N900 owners able to see any networks other than Rogers/Fido?
