Nokia Bringing E63 To US

When a phone supports "U.S." 3G, it also supports Canadian 3G, and there's no AWS band on any Canadian carriers. Nokia is positioning the device to sell as many units as possible, so they'll want a device which appeals to the larger number of users. Thus: it's compatible with AT&T 3G as well as Rogers. Not a lot more customers, but certainly much more than if they just had AWS 3G for TMobile only.

As side note, I'm not sure why they don't produce more phones that are quadband GSM/triband HSPA (850/1900/2100), as so many other manufacturers seem to be doing, but they're the #1 phone seller in the world, so they've got to have some reason (possibly related to chip production costs).
