or at least maybe in the search when you're looking for phones.
As for covering Canadian carriers, it's a matter of limited resources. The official focus of this site is the U.S. market. There are smaller U.S. carriers (SunCom, Cellular One, etc.) that I don't have the resources to cover. That would come first, before expanding internationally.
I do appreciate the feedback, however. Thanks!
