This is exactly what I want to do with the Verizon device payment plan. Pay it off and just either buy the X outright or through the Apple Upgrade Program. The less I am tied to Verizon the happier I will be.I plan on going with the X so I have time. Unfortunately I'm enrolled in the Next program with AT&T so I'm debating maybe next month either paying off the full amount so I'm free to get an X without having to trade in the phone. It looks like I could re-sell the phone on ebay for the same price I owe on it anyway that might be a better deal in the long run.
