Today at Apple's annual World Wide Developers Conference keynote, CEO Steve Jobs announced the new iPhone 4, the sequel to the iPhone 3GS. Jobs said the new iPhone is 24 percent thinner than its predecessor, and features a front-facing and rear camera, a micro SIM tray and "glass on front and back for optical quality and scratch resistance," Jobs said. The 3.5-inch display is 326 pixels per inch (960x640 pixels) "so everything will look like continuous curves to the eye," he noted.

It features up to 32GB of storage and the battery life is impressive -- seven hours of 3G browsing, 10 hours of Wi-Fi browsing, 10 hours of video, and 40 hours of music.
