Nokia never made much headway in the USA because all of their good models were GSM phones -- in the US that meant t-mobile or AT&T -- and back before the iPhone appeared most US cell phone users were on CDMA networks (Verizon and Sprint.) Nokia decided to roll their own CDMA chip instead of paying off Qualcomm (big mistake) and ended up with a weak presence in the CDMA market. Nokia screwed the pooch all on their own when it came to fumbling the US market.
