People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With the tap of a button, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories — iPhone 4 to iPhone 4 over Wi-Fi. No other phone makes staying in touch this much fun.
