Reliable French leaker Steve Hemmerstoffer via his blog NowhereElse.fr and Twitter handle @OnLeaks published this morning another claimed technical drawing of Apple's forthcoming iPhone 7 which suggests that the device will be as tall and wide as the current-generation iPhone 6s, measuring in at exactly 67.1 mm wide and 138.3 mm tall.
The leaked drawing does not specify the depth of the iPhone 7, but previous rumors did point to an iPod touch-thin phone so it's too early to tell if existing cases will fit the iPhone 7 or if these will need reengineering for a thinner form factor.
