iPhone 4 has over a hundred new features, with a focus on an all-new design that is considered one of the most beautiful and precise designs ever made by Apple.
The design includes glass on the front and rear, a stainless steel band, and is incredibly thin at 9.3 millimeters, making it 24% thinner than the iPhone 3GS and the thinnest smartphone globally.
The stainless steel band around the phone serves as the primary structural element and houses integrated antennas for both UMTS and GSM, showcasing innovative engineering.
External features include volume controls, a front-facing camera, receiver, home button, micro sim tray, camera with LED flash, microphone, 30-pin connector, speaker, headset jack, a second mic for noise cancellation, and the sleep/wake button.
The design's use of stainless steel for strength, glass for optical quality and scratch resistance, integrated antennas, and exceptional build quality sets it apart as a unique consumer product.
