Hey man,
I'm from Ontario, using an unlocked iPhone (fw 1.1.2) on fido. I did it myself.
To be honest, the outlook of a canadian iphone is both plausible and at the same time questionable, but all for good reasons. Rogers data rates (for one) are insane. 10mb/10$ where att gets unlimited. unless rogers can make a means for this, it is unlikely.
I'm sure if you google around, people are stating iphone will be released, but check to sources.
As for me, i bought one opening week (yeah i ventured to new york to buy one) with the thought of it coming to canada - honestly, eBay is you best friend. if ever v2 comes out and is released in canada, you can always eBay it. people will be willing to shed out 300 for the phone (sure you will lose 100 bucks or so, but whatever)
one last note. if you are considering buying and unlocking the phone. be cautious of where. sure you can ebay it, but note if it is unlocked or not.
if it is not unlocked, make sure check the firmware as well as week that it was released. apparently all the new phones have a 4.6 bootloader version that cannot be unlocked with a free unlocking method and need a simunlocker tool to do so.
but yeah. it is wishful thinking until apple confirms ANYTHING
