hey everyone. So i currently have the iphone 5s and have upgraded to the new ios10. I'm perfectly find with it, but i would like to get the newer features of the 6s or 7. I'll be going back home to nyc this week for a visit (i currently live in Australia) and my mom has offered to buy me an iphone 7. Im not too thrilled with teh lack of headphone jack, as i do need it since i travel alot and I know i can get an adapter for the headphones if i did decide to charge the phone and listen, but i think i would prefer less parts to carry around. Lack of headphone issue , is there anything else that i would lose of if i were to get the 6s over the 7? I don't really care about the camera. This phone would last me around 3-4 more year (unless the next model is mindblowing). I would be going though ATT as well, so would they unlock the phone for me straight away or would i have to wait? I'll only be in nyc for about 2-3 weeks. Thanks.
