Personally I'd have preferred it if Nokia had a nomenclature like "Lumia 920 CDMA" or "Lumia 820 for T-Mobile".

AFAIK, Verizon had a crappier Nokia WP while AT&T got the shiny 920. The 928 could be just be for making Verizon users feel like that they got the latest and greatest rather than a late phone model.
