Best Verizon smartphone out there under $200?

Never had a smartphone before so I want something that will last. Need some ideas.

only things I really want are:

atleast 16gb memory as this will be my mp3 player and everything. So removable memory is wanted as well.

Prefer a removable battery - long battery charge.

Make good clear calls since it is a phone after all.

I know nothing about the best apps, maybe someone could help me with that.

Thanks!!
