Taller Next-Generation iPhone Front Panel Caught on Video
Japanese blog Mac Otakara has now gotten its hands on one of those front panel parts and posted photos and a video comparing it to the current iPhone design. As has been shown by leaks so far, the next-generation iPhone would be somewhat taller than the current model, with estimates putting the difference in height at roughly 10 mm.
Roughly in line with the design schematic leaked yesterday, Mac Otakara measures the display opening at 10.33 cm (4.07 in) diagonally, allowing a 4-inch display as has been rumored to fit within the opening.
