The answers really depend on how you define "US 3G". If you're going to call EV-DO 2.5G, then the answers to your questions are both "True".
But, most people (around here, anyway) consider EV-DO to be 3G. In which case, the answers to both are "False".
In other words, if the person you were originally having this conversation with considers EV-DO to not be "3G", then the other stuff they said is mostly correct.
