Meet Apple’s GORGEOUS New iPhone 5

Leaks are turning into floods as whisperings and conjecture grow into full-fledged rumors ahead of Apple’s (NASDAQ:AAPL) Worldwide Developers Conference. While a new software launch seems likely, what everyone really wants to know is what new products Apple will present this week.

Most of the attention has been centered on the Mac lineup, which has grown stale in recent years as Apple focused more on its mobile devices. Anonymously emailed photos of spec sheets point to new MacBook Airs and MacBook Pros, expected to use Intel’s (NASDAQ:INTC) new Ivy Bridge chips. But the most recent leak seems to be a video of the alleged next-generation iPhone.

The video features a side-by-side comparison of an iPhone 4S and a backplate identical to a part seen in previously leaked photos. The video gives a highly-detailed look at what appears to be an aluminum backplate first seen in May. If the video does in fact show the next iPhone, it will be a huge departure from the chassis and back glass of the current iPhone 4S.

The side-by-side illustrates how Apple’s next iPhone could sport what the narrator of the video calls a “uni-body” design, which does away with the back glass in favor of a metal chassis and front glass configuration. In fact, the “new” iPhone would be more of a regression to the design of the iPhone 3G/3GS that had internal components packed into a rounded polycarbonate shell.

However, though the new chassis is thought to be aluminum, it looks like Apple has managed to cut the fat, allowing for a markedly svelte profile not seen in current Apple handsets. n the video, the new component is markedly thinner than the iPhone 4/4S metal mid-section alone.

As the narrator moves on to other sections of the phone back, he notes that the SIM card trade is significantly smaller than the piece found in the current iPhone 4S, thus making the two parts incompatible. The SIM tray could feasibly fit the new “nano-SIM” format recently adopted by the European Telecommunications Standards Institute.

The narrator also notes the much-rumored “mini dock” at the bottom of the unit — so say goodbye to cord compatibility until you’ve upgraded all of your Apple devices.

Thursday’s leak comes less than a week after a video was released claiming to feature the next-generation smartphone’s front glass. Though it’s unclear how thick the assembled shell would be with both sections put together, Apple is rumored to be using in-cell display technology to keep displacement down. Both parts point to a display with a diagonal length in excess of 4-inches, in keeping with rumors that the new iPhone will boast a bigger screen.

Unfortunately, it may be a while before the true composition of the next-gen iPhone is known, as Apple is expected to debut the new handset this fall, between September and October, and not at WWDC this week, where an all-new Mac lineup is expected to take center stage.
