But a job?

and can we join if we get the iPhone 6 without contract and trade iPhone 6 in and than get the iPhone 6S free once it comes out?

I don't believe you're allow to do Jump On Demand without a credit check. You have to be on their Simple Choice plan. They have a Simple Choice No Credit Check plan but that one doesn't let you do Jump On Demand.
