The stainless band is really unique because it's the only Apple product I can think of that has the stainless steel not polished. I have a 32GB black GSM 4 along with a matching box, a 16GB white CDMA 4, and a 16GB black 4s.
The black 4 works on iOS 7.1.2, but the battery life only lasts a few minutes because the seller said the phones (4 and 4s lot) were in storage for years, which makes sense with the toll it could take on the battery. Power button doesn't work so I may end up doing a battery and power button swap with the white one.
The white 4 is activation locked.
The black 4s works on iOS 9.3.5, but I have jailbroken it and might try to downgrade it to iOS 6.
Although the 5s is my favorite design, the 4 is an easy second place.
