With the iPhone 5 just over three months old, rumors and information have already begun to surface about Apple's next generation smartphone. The evidence so far points to summer 2013 as the tentative release date for an iPhone 5S. Apple is likely to improve on the iPhone 5 design with internal upgrades, while keeping the same form factor.
Photos have purportedly been leaked showing the back panel of the iPhone 5S, which exhibits several minor differences from the current iPhone 5 chassis. Most notably there are two screw holes on the inside of the backplate that have been shifted to a slightly different location. ETrade Supply released several photos showing the inside and outside of what they claim is the iPhone 5S housing.
