The one that is in the 2 year contract will not be avaible for a long time due to you just upgrading. As fair as the other one (1 year contract) should be ready for the early edge soon. Yours could have been the lucky one to get picked for it.
When you are offered the early edge, you usally only have a few phone to pick from. Currently it is only the Droid Turbo or the Droid Maxx.
I would just wait until all your phones are out of contract, becouse you can chose any phones.
