The dimensions of the next generation iPhone already made news when alleged photos of a 4G replacement touchscreen and digitizer were released. The newer version was 1/4 inch (6 mm) taller than its predecessor and appeared to have space at the top or even a cutout for a possible front-facing camera.
Now a video of the same part has hit YouTube, and the appearance of the replacement LCD and digitizer assembly looks very similar to the photos we've already seen. Soundtrack selection notwithstanding, this video clearly shows an elongated iPhone screen. That being said, Apple has been known to change specs on its products anytime before launch and will never let on before an official unveiling.
