The fourth generation of the Apple iPhone has been spotted in the wild, according to the tech blog Gizmodo. What appears to be a prototype of the yet-to-be-announced device was "found lost in a bar in Redwood City, camouflaged to look like an iPhone 3GS," according to the blog.

Nothing gets the Internet abuzz more than a new Apple product rumor, but this has got to be the most unusual leak yet. Gadget sites like Gizmodo usually feature fuzzy cameraphone shots or the occasional photoshopped fake, but this one is an actual hands-on device that they were able to tear down and view the Apple-branded internal components.

According to the report, the device runs the as-yet-unavailable iPhone OS 4, has a front-facing camera (to make video calls), a more traditional back-facing camera for photos, higher resolution screen and other slick features. Check out the Gizmodo video breakdown with additional details.

Even before this device was found, the Apple faithful anticipated the company would unveil a new iPhone at the next Worldwide Developers Conference. Apple has yet to announce a date or location for the event, but the smart money is for June 28 – July 2. That’s because San Francisco’s Moscone Center has been reserved for those dates for a “corporate event”—which is the placeholder name given for past Apple events—and it’s also the three-year anniversary of the original iPhone launch.

In addition to unveiling a new iPhone, Apple also is expected to announce a new wireless operator partner—most likely Verizon Wireless.
