Rumors regarding the next-gen iPhone is all over the net already. Now a latest leak by Japanese blog Macotakara suggests that the next iPhone would be taller than iPhone 4S. Macotakara 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.
Technically speaking the estimated height difference is roughly 10 mm. In the photo below we can see that the display measures 10.33 cm (4.07 in) diagonally. Also the difference between the size of the home button height is slightly smaller than the iPhone 4S.
