I'm flying to D.C. this weekend to visit a friend & try to snag an iPhone. I have a U.S. SSN from a few years ago, and a U.S. address -- hopefully it works out.
Roaming in Canada will be a bit pricey, but between my work use of the phone (which pays for a large chunk of the bill) and my existing Rogers phone, it probably won't be too bad.
One thing I note on the recent reviews is that everyone is discussing the missing features & oversights, but few are discussing the reason why all of this is irrelevant, and why the iPhone really does change the game: it's just software, folks. Apple will issue updates regularly -- that will auto-sync whenever you dock the phone with iTunes.
Sure, they can't fix the fact that EDGE is slow (it's not "ancient", and is pretty good, by the way, in Canada, even in rural Ontario areas, and it's a lot faster than GPRS was). But, cut/copy and paste? Instant messaging? MMS? MP3 ringtones? Surely these were triaged and didn't make the cutoff date. Apple will get there....
