I want to upgrade to a iPhone but my 2 year contract isn't over?

I want to upgrade to an iPhone but my two year contract isn't over. What do I have to be able to do the upgrade early to an iPhone. If I upgrade now the upgrade would be a year early. Is it possible for me to upgrade now if so give description and what I'm supposed to do

It all depends on the carrier. Call up customer service for your carrier and ask what options there are for you to upgrade you phone now.
