If i wanted to get a new phone and keep my same contract what would i have to do
Your question isn't totally clear....to me anyway. If you want to keep the same options (# of minutes, text plan, etc) then you probably can, providing the new phone you choose will work with your current plan. The new phone may require a data plan, in which case you would need to add that.
If you mean you want to add a new phone without extending your current contract for 2 years, then you need to use a phone from a source other than Verizon (ebay, craigslist, a friend), or pay full retail price at a Verizon store so the 2 yr contract isn't needed.
If neither of these interpretations is correct, post back and clarify!
