I have an iPhone 6 Plus 64GB (space gray). I have figured out that the lightning port is bad, it will stop charging/syncing with the slightest touch/movement and some cables don't work at all. I've resigned myself to replacing the phone out of warranty. Apple quoted a 329 price for replacement. I have a couple of questions before my genius appointment next week. Do they make any attempt to repair or do they only do replacements? Do you know when they replace the unit if you can change from one color to another or are you stuck with the identical model you had? I wouldn't mind changing colors if possible. Also is there any discounted upgrade path available instead? So instead of paying 329 for a replacement could I get a 6S Plus 64gb for a little more with a 'trade-in' or will that not be offered since it's broken?
