iPhone fans are about to have a new toy to play with. The iPhone 4 — available for preorder June 15 — has a bunch of cool features, including our favorite: video calling (courtesy of a new, front-facing camera). And now the camera on the back of the phone can shoot HD video. Thanks to the highest resolution of any phone screen out there, videos will look better than ever. Like the one we’ll be taking of us grinning from ear to ear.
