I met some friends at North America's largest Indoor Asian Mall this afternoon and thought I'd Qik it for your viewing pleasure...
You can indeed buy working, unlocked DoCoMo handsets from at least one store here, even though you can only talk and text on them. And despite my lukewarm reception at said establishment I'll give them a plug anyway:
Pacific Mall Unit D53
Phone: (647) 728-3388
Here's a floor plan of the mall if you're heading up... Be sure to tell them who sent you!
