I also made it to the Apple Store where I was able to pickup and lease my 7+ MB 256 and my wife's 7+ RG 256. We had preordered a 7+ JB 256 and a 7+ RG 128. Anyway. They had the reservation. When he asked if we were doing IUP we said no. I explained I wanted to try to see if I could lease through sprint, I told him he needed the iPad. He got it and we worked through the process with him and a coworker. Between the 4 of us it took some time... about an hour to get my phone to go through. Once we knew the process and what info we needed where we were able to fly through my wife's in 10 minutes.
We walked out paying $0 for two iPhone 7+ 256gb phones. All leased through sprint.
