A new video surfaced Wednesday that appeared to combine several iPhone 4S parts with the next generation iPhone, largely rumored as "iPhone 5," showcasing changes rendered with regard to flex cables and screen size.

The video hosted on YouTube by a firm named SmartPhone Medic does not disclose much information, except providing a few close-up shots of parts supposedly belonging to the sixth-generation iPhone, AppleInsider reported.

Initially reported by MacRumors, the parts featured in the video include front panel and flex cables for external controls, dock connector/ headphone jack. Though features of "iPhone 5" were leaked previously, the video provides another look at what changes can be expected in the next generation iPhone.

It is widely reported that Cupertino-based Apple is expected to announce and take pre-orders for the next generation iPhone and iPad at a special event September 12, with the unit rumored to be made available in the U.S. September 21.

The video appears to offer a comparison with Samsung Galaxy S III that seems to fit the entire front cover of the Apple handset shown enclosing boundaries of massive 4.8-inch diagonal display.

Comparison of flex cables belonging to iPhone 4S with the next generation iPhone appears to be the highlight of the video. While the iPhone 4S flex cables appear to host the headphone jack, volume rocker and vibrator switch, "iPhone 5" counterpart comes with a sleep/ wake button control while foregoing the jack.

Though the new components or circuitry were found in the next generation iPhone, Apple's experts seem to have reconfigured the iPhone parts to make room for battery that can power a 4-inch screen. Another prominent variant happens to be the downsizing of Apple's 30-pin connector to 9-pin. This apart, the headphone jack is spotted at bottom of the handset similar to iPod touch, and bears semblance to service antenna as well.

The Apple (AAPL) stock continued its tear closing August 22 at $668.87, 1.95 percent above the previous close.
