In a nutshell: The iPhone 3G is an amazingly user-friendly touchscreen phone. It includes many powerful features such as GPS navigation, OS X applications, fast web browsing, Apple''s famous music-playing capabilities, up to 16 GB of built-in memory, and Wi-Fi support. But at the same time it''s a very expensive device that misses a number of features that we''ve come to expect from high-end smartphones. We recommend the new iPhone 3GS.
