Whatever would work out to a $200 profit for me. I have a brand new iPhone 5 that works just fine. Honestly, part of the reason I ordered the 6 was because it's silly to NOT order. By being on a subsidized 2 year contract, the cost of the subsidy is built into my bill already. If you don't upgrade at the 2 year mark you're essentially LOSING money.... plus I have it set up so that I upgrade one year and my wife does the next year. I like it that way. I'm sure one of these years we'll probably NOT want the updated hardware but will upgrade to it just to sell it. I'd do it this year for a $200 profit.
