2. Its a little bit taller, lighter, and screen is bigger (4 inches)
3. Updated chip (Which basically means its faster)
4. Sprint, Verizon, At&t, and T-Mobile will have it
5. It has Touch ID where you can lock and unlock with finger print scanned
6. Still a 8 Megapixel camera but it has been updated tremendously with what they call iSight
7. There is slo-mo video and you can take pictures while recording also
8. Battery last longer

Oh yeah, the picture below is the new phones...that's it.
