Apple iPhone 4 – QT Teardown Summary
• While maintaining a similar form-factor and display size to preceding iPhone designs, the iPhone 4 introduces a much higher-resolution LCD, improved camera with LED flash, additional video-call camera, and faster operation speed among many new features and a next-generation OS.
• The case design indeed seems to implement a unique integrated antenna design, with co-molding used to create isolated sections of edge frame to enable radiation and reception for the Cellular, GPS, and WiFi/Bluetooth radios.
•The Apple-designed, Samsung-manufactured A4 applications processor with ARM A8 Cortex core makes a repeat performance in the iPhone 4 after its debut in the Apple iPad family. In an upgrade from the iPad A4 implementation, applications memory has been doubled from 256MB to 512MB of Mobile DDR SDRAM (still using a x64 interface) in a Samsung-manufactured package-on-package.
• The iPhone 4 introduces new part numbers in the cellular engine while maintaining the same general vendor set as seen in previous Apple cellular implementations |
