Well, IIRC Rogers does have some AWS spectrum and plans to (eventually) expand onto it, which would be T-mo US compatible. Not sure how soon or how geographically wide-spread that would be... And of course, saying you "can't actually use it" is like telling many T-mo USA customers (my town, for example, is EDGE-only for another couple months) and all the original iPhone purchasers they can't use their data connections. No denying that EDGE is inferior, and I'll be plenty excited when 3G arrives, but as someone who uses it everyday, I must say it's a long way from useless. If you can confirm that Rogers will roll out AWS 3G in your area eventually, it could be reasonable to run with EDGE temporarily.
