I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
I'm in SC and have had an issue all day with my phone not calling out and not receiving calls. I have a 4s so still receive 3G but according to the link above Verizon is saying only 4G...hate to inform them but it's also 3G.
