Verizon cell phone upgrade?

I have the LG Voyager and my contract ends in early December...my Myverizon thingy says I'm eligible for an upgrade though. The hinge on my phone just popped off the other day and I'm going in to get a new one. If the phone is being upgraded, do I have to pay anything? And would I be able to get a phone like the Droid as an upgrade?|||pretty much you would pay the price to get the phone say the phone is 199$ you would pay the 199$ compared to 400$ or so and sometime you get 50$ off just call verizon or go to your store they will help you every step of the way|||You would only have to pay the upgrade fee $18.00 and the price of the phone you want. Yeah you can get the Droid as an upgrade.
