Apple's iPhone 4 promo videos show Retina Display and video calling

Ready to be uplifted by soundtracks and low swooping device shots? Apple's just posted up its iPhone 4 design video, a video about the new Retina Display, and the new (leaked) FaceTime commercial directed by Sam Mendes, and they're all pretty fun. Check 'em after the break.

Update: We're told this isn't actually the Sam Mendes video calling ad, but rather an Apple promo video produced internally. We'll just have to wait and see if Mendes can top these heartwrenching images of American beauty with his ad.
