So I dial *3 to pay my bill by MasterCard (and get the giant rebate that
card offers me); and it asks my Sprint Number, and then my billing Zip
code, and it won't accept it. Says its not valid. Strange, its been my
billing zipcode the whole time I've been a Sprint customer.
No problem, I went to the SprintPCS website, and paid there (2 weeks
early: per usual).
