Yet Vodafone alone has 427.99 Mill customers as of March (Vodafone's service is Unified worldwide, so it is a fair comparison). Wouldn't it be far more profitable to try reach out to more of these customers, than to gain only a fraction on Verizon? Nokia is in fantastical love and control over GSM markets, there's are far bigger potential for Apple to eat Nokia's Smartphone lunch than to serve a vocal minority. (That makes VZ less than a quarter in subscribers, than that of not even the biggest GSM provider BTW)
Verizon isn't the ONLY CDMA carrier on the planet. It would work on Sprint to as well as in many other countries with carriers that use CDMA. It appears that there are 480 million CDMA subscribers world wide.
