So I did the iPhone 7+ upgrade through T-Mobile and is time to turn in my fully unlocked Apple Store launch day bought iPhone 6 in. Now the problem is that my iphone 6 has been suffering from the touch disease and it got unbearably worse until I got my 7+ (how convenient, huh?). Do you think the problem might flare up during mail trade in to T-Mobile? Would it get rejected? The phone is in pristine condition without a single scratch on it, no water damage. Only problem is having to bend the phone a bit to get the screen to work properly... Anybody else on a similar situation? Suggestions?
