If you decide to buy one, make sure you select the right one :-)

My understanding is that Rogers, Telus and Bell use the same frequencies, so if you pick the “AT&T and Rogers” version, wouldn’t it be fine for Telus and Bell too?  [ edit: apparently, the answer is no: http://www.thestar.com/entertainment/article/780601--google-s-nexus-one-phone-now-available-in-canada?bn=1 ]

And wouldn’t the T-Mobile version work for Wind Mobile? [I'd really make sure before buying!]
