How can I get the rapture phone without making a new plan for verizon?

I have a crappy phone that I want to update. I've been eying a specific phone, the Rapture, but it's not in the list for upgrading my phone! I really don't want any phone except that one so how can I get it without making a new plan?

I tried this and it fits my needs.
