A hands-on video of what is claimed to be the external housing for Apple’s next-generation iPhone has been published on YouTube. Cell phone parts retailer ETradeSupply managed to procure what it says is the unibody aluminum case Apple will use on what it refers to as the “iPhone 5,” which BGR expects to launch this fall. The iPhone casing appears identical to the housing that appeared in a number of leaked photos published by various websites last week. Visible in the video are a new, smaller port for a redesigned dock connector, a relocated headphone jack, new speaker grills and a taller design that will reportedly be home to a larger 4.08-inch display. The case appears to be significantly thinner than the housing found on the current iPhone 4S and iPhone 4, and the unit will supposedly make use of a new smaller SIM card. The full hands-on video can be seen below.
