Comparison pics show Apple's slight changes in alleged 'iPhone 5S' front panel

A new side-by-side comparison of iPhone 5 parts with components allegedly built for Apple's next-generation "iPhone 5S" show minor internal changes, the most significant of which is a longer ribbon cable attached to the front display.

The direct comparison of front panels was first published Fanatic Fone, once again suggesting that Apple's unannounced next-generation iPhone will sport largely the same look as the iPhone 5. That's why the rumored device has been dubbed an "iPhone 5S" by media and fans, who expect the handset will sport an essentially identical design to Apple's current flagship smartphone.

Aside from a longer and redesigned ribbon cable on the front panel, the rest of the part looks mostly the same, with a few internal changes in the form of moved screws and other minor tweaks. But on the outside, the part looks identical to the iPhone 5, with the FaceTime camera remaining directly above the handset's earpiece.

Screw placement around the "iPhone 5S" home button is also essentially unchanged. Rumors have repeatedly suggested that Apple plans to embed a fingerprint scanner inside the home button of its next iPhone, but so far none of the leaked parts have offered any evidence of significant hardware changes.

Apple is expected to hold an event at some point in September to unveil its new iPhone lineup for the fall of 2013 and beyond. In addition to a next-generation flagship "iPhone 5S," Apple is also expected to introduce a new low-cost iPhone with a plastic back and the same 4-inch display as the iPhone 5.

Apple's overseas supply chain partners are said to be in the process of gearing up to begin manufacturing the company's next handsets. It's expected that the "iPhone 5S" will include the usual annual upgrades, such as a faster processor and improved rear facing camera.
