HOW MUCH IS AN EARLY UPGRADE WITH AT&T?

I can't actually upgrade till 4-24-14 (When my contract expires) and I broke my current phone (iPhone 4s) and the warranty expired, so I can't replace it without buying a new phone to begin with. This is my first cell phone with AT&T, so I don't have another one to switch to till I can upgrade. So I was just wondering how much it would cost to just upgrade to an iphone 5… I might as well considering my 4s is broke. :/

You normally won't get any of their phone for a lower fee. The only way you do is if your contract is up and that is how they get you to stay with them for another 2 years, by bribing you with a lower cost. If your contract isn't up, you can't upgrade. You would have to purchase a phone at full cost. You can however use another person's upgrade. If you have a family plan and someone else on the plan has a contract up, you can swap upgrades by signing them up for another 2 years and taking their upgrade. And you said this is your first time with AT&T so that probably isn't an option. Your best and cheapest alternative would probably be Craigslist.

The obvious answer is to call AT&T and ask THEM.
