In June 2010, Apple diverted from previous designs with the iPhone 4. Featuring glass front and back, a front and rear camera, and 512 MB RAM, the iPhone 4 met a highly favorable reception. The iPhone 4 is the first iPhone with video conferencing capabilities over Wi-Fi. It runs the A4 Processor just like the iPad. It has 5MP camera with LED flash and shoots full 1:1 720p video at 30 FPS.
