白色哀鳳4比起黑色多了兩項改進,一個是Proximity Sensor Opening一個是改進了Death grip
Death grip 就是當初黑機上市時因手握位置造成訊號嚴重衰減的問題,這點大家應該都有耳聞而不用多解釋吧
厚度,看起來有差,測試報告實際差0.2mm, Apple官方並沒有證實

In an interview with All Things Digital yesterday, Apple Senior Vice President Phil Schiller said that in making the white version of the iPhone 4, the company found it needed to rework its manufacturing processes to make it more durable. That included extra protection against UV. "It's not as simple as making something white," Schiller said. "There's a lot more that goes into both the material science of it--how it holds up over time...but also in how it all works with the sensors."
The white version of the iPhone 4 sports a clearly noticeable version of the proximity sensor, which sits just above the top speaker grille. On the black models, this is a detail that disappears with the rest of the bezel. Early imagery of the white iPhone 4 had that sensor appearing as a fine mesh of dots, akin to the way the company hides notification lights on its notebook computers.
Other small changes picked up by iLounge include that the headphone and dock ports in the white version get a color treatment, with Apple opting to use a gray plastic material, presumably to better blend in with the company's bundled headphones and dock adapters.
. Proximity Sensor 這個功能.黑的早就有了好嗎.
