ok my brain is just not kicking in today. It is no big deal to me to get an iphone 6 or 6 s. my question is this: I currently have an LG G4 with ATT on the NEXT plan. If I trade in now it is $422.00 plus the phone. to pay off in full is $577.00. I would have to sell it to do the $577.00, so no phone. They are not going anywhere close to that on Craigslist or Ebay. Maybe $375.00. On ATT's site, they trade in is $150.00. I have a little to put with whichever way. So what would be the best option?
