iPhone 5 rumors: 4-inch screen and unchanged form is possible, designer says

Recent reports on the iPhone 5 claim that the handset will sport a 4-inch screen.

This has raised the question of whether Apple will keep the form of the smartphone unchanged or they will redesign the entire case according to the new display.

Designer Will Hains at Good Will Blogging believes that Apple could keep the same sized device and still use a 4-inch display for its next smartphone.

These images present a concept of a possible iPhone case maintaining the same dimensions with a larger screen.

What do you think? Could Apple intend on equipping the iPhone 5 with a bigger screen and keep the same form factor? Is this a possibility?
