How to upgrade to a new iPhone 5s for free? How can I do it?

Are there any holiday promotions going on for cheap/free iphone upgrades? I have a really old flip phone and its about time I upgrade to a fancy new apple iphone i think. Can someone help me out, what's the best deal possible for an iphone 5s? Do any providers offer free iphone 5s?

I doubt it. There might be software updates (I don't know about Apple, but Samsung do it for free) which can upgrade your firmware and your phone build. I doubt that any of that will COMPLETELY update it to the new iOS.

If you are on Verizon, AT&T, or Sprint there's currently a holiday promotion thing going on that will let you upgrade your current phone to an iPhone 5s for free. The catch is that you will have to extend your contract with them for 2 years. It's still a pretty good deal (free iphone, can't complain at all!)

I got my iphone 5s from this. You need a special promo key for it to work, but you can get one from here:

all you gotta do is add the promo code to your shopping cart on your cell providers website and they will credit you for the free upgrade. Its really easy, but keep in mind you will have to extend the contract by 2 years!
