Verizon is holding its own in the US wireless market selling 3.2 million units this year. Better yet, Verizon sold 850,000 LG Chocolate phones in Q3, which means that while a million Apple fans have trouped to stores for the iPhone, Verizon is raking in a respectable amount of customers.
I guess Verizon shouldn't be worried about the iPhone at all. They're currently selling Chocolate Phones for less than $100 with a contract.
