I use BlackBerrys on Bell and Rogers, as well as an iPhone. Was able to successfully install the BB beta on my Rogers 8900 (crashes on 9700), haven’t tried iPhone yet but if it won’t work in Canada, there’s no point in my even trying it out at the moment. Thanks.
I’m in Canada too but have yet to try it out (at work right now). It loaded up fine on my 9000 and I was able to see the map on the website just fine (editing location) but nothing on my BB because I can’t get a GPS signal while inside.
OK, so it works on my BB 8900 ok, but it works great on my iPhone 3GS. I’m in Toronto, using Bell iPhone and Rogers BB.
Works great for me on my iPhone 3Gs. I’ve been from Sarnia, over to Toronto, over to Goderich and as far north at Temagami and it always seems to know where I am. Routing… well that is another issue but it is getting better! 
Oh yea… most of my time I’m in the Cambridge, Guelph, Kitchener area…
