iPhone 4: Still a Smartphone Leader

The first reviews for the fourth generation iPhone are rolling out, and surprise, surpise, they are full of praise: The iPhone 4 delivers "a big, well-designed update that, in my view, keeps it in the lead in the smartphone wars," writes Walt Mossberg at The Wall Street Journal. The iPhone 4 has a new look: a sharper screen, larger battery, rear camera with a flash, and is thinner than its predecessors. The phone also has a front-facing camera with video capabilities, and the video software, FaceTime, reinvents calling. But there is a downside: The iPhone 4 is still on the overwhelmed AT&T network, which has poor network reception in many cities. After being overwhelmed with pre-orders, the much-coveted device is going on sale (again) June 29, five days after the anticipated release.
