THE GOOD: The iPhone 4 offers enhanced performance, a lovely new display, and an improved design. It also adds a ton of sorely needed features, both by itself and through the iOS 4 update.
THE BAD: Multitasking entails some trade-offs, and home screen folders are limited to 12 apps. AT&T reception continues to be spotty.
THE BOTTOM LINE: With iPhone 4, Apple again shows that it is a powerful player in the smartphone wars. It won’t be for everyone, and AT&T remains a sticking point, but the handset’s striking design, loaded feature set, and satisfying performance make it the best iPhone yet.
