iPhone 5 prototype leaked ahead of today’s launch in San Francisco

Apple is ready to unveil the new iPhone 5 to the world in San Francisco today.

Meanwhile a video, which was purportedly filmed in an Apple factory, with the user taking great care to hide any serial numbers which might identify where the phone comes from, emerged to the public.

The video shows off the iPhone’s larger display, and the dock port which has caused much consternation for Apple fans who own accessories and cables which will not fit the new model.

The latest video has already had four million views on YouTube since it appeared on Asian website vgooo.com.

While these leaks should always be taken with a pinch of salt, it follows the design pattern for the iPhone 5 which has been rumored for months.

In the video, the new handset’s controversial connector can be clearly seen, along with the larger 4 inch screen.

The user went no further than the “connect to iTunes” messages on the screen, perhaps in fear of being tracked and discovered with an unauthorized model.

The video follows a leak last week which also claimed to show an iPhone 5 next to an iPhone 4S, which was posted by an anonymous user to YouTube.

Meanwhile, a Taiwanese pop star casually shared photographs of his brand new “iPhone 5” with his 13.5 million followers on Weibo, the Chinese micro-blogging equivalent of Twitter.

“Today I confirmed that the iPhone 5 will be longer and have an aluminum back like the iPad,” Jimmy Lin wrote, sharing that the new Apple phone will indeed have a smaller USB connector, much to many’s chagrin.

Though information has been known to leak about Apple’s secretive phone updates, many have dismissed Jimmy Lin’s new toy as just another knock off.

After Jimmy Lin shared several photographs of his new device, it was shared more than 80,000 times across the web, according to The Next Web.

“While it has a four-inch screen, it’s thinner, though it feels about the same in the hand,” he said.

“The headphone jack has also been moved to the bottom.”
