How do phone upgrades work for AT&T?

Verizon Upgrades For Dummys Please?!?

• I'm used to pre paid phones this is my first contract and I have a Droid Incredible I want to upgrade to a Droid Incredible 2. How do upgrades work? You don't just trade in the old for the new lol what do you pay or what determines how much you pay? Also what do you do with your old phone? Can you sell it or do you have to pay AND trade in your old phone? Any advice on how much I will need for the Droid Incredible 2? thanks in advance!!! -Elektra

• Answer:

  If you're eligible for an upgrade then you can get a phone for the upgrade price. If you aren't eligible yet, you can still upgrade but you will have to pay full price for the phone. You can do whatever you want with the old phone once it's deactivated so long as you don't have any outstanding charges or something you haven't paid.
