Earlier this month leaked images showed up displaying what was allegedly the steel chassis/antenna of the new iPhone. There was no definite clue as to whether this would be the iPhone 4S or the iPhone 5, either way it was unique. (Some are debating whether or not a 4S will launch alongside the 5, or if the 4S is the 5.) Thanks to some MacRumors readers, the site now has more detailed comparison photographs. The images show the new antenna design next to the CDMA iPhone antenna and the GSM iPhone 4 antenna.
The shape and dimensions are exactly the same. The only real difference is where the antenna breaks are. The new design shows the breaks as being on the top and bottom of the left and right sides of the steel frame. Unlike the current GSM iPhone 4 there is no break near the 3.5mm headphone jack. If it’s genuine, my guess is that because the next generation device will have a dual mode chipset compatible with both GSM and CDMA bandwidths, the structure had to be altered.
