So I had a lemon iPhone 6 bad vibrator mechanism made a terrible clanking sound. Screen was dark in the right hand corner, and finally a small spot under the glass right by the ffc. Anyway I took it to T-Mobile yesterday since I was still with in my 14 day period to return it and they set me up with a warranty replacement because of the jump warranty. Since they didn't have any in stock at the store they overnight shipped me a iPhone 6 (just the phone) as a replacement and I just got it and wow it is a lot better than my first iPhone 6 it is considered "refurbished" but when I took it out of the box it looks as if it was taken out of a retail box the screen looks great and not more clanking sounds. The main reason for this was to say I had sprint for years and never did I receive this type of service during the 6 years I was with them.
