I pre-ordered my iPhone 4 on the 15th and to my surprise, Fed Ex delivered it today. Considering Apple and AT&T put pre-orders on hold due to high demand, I wasn't expecting it until after the 24th. The retina display is insanely nice and the multitasking and folders option on iOS4 are great. It's thinner than the 3G but feels heavier and whereas the 3G has curvature, this one is flat in the back. The front/back facing HD camera is . All in all I'm loving it! Anyone else thinking of getting one or already have one? Thoughts?
