Apple 對於如果拿 iPhone 4 時因為手碰觸到左下方金屬部位,
可能造成收訊不良,有了回應:
Gripping any mobile phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone. If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band, or simply use one of many available cases.
就是解釋說,用手拿手機多多少少會影響天線,如果遇到問題,避免那樣拿、或是裝個殼吧!

Engadget 轉貼了一段當年 iPhone 3G 上市時,
也曾發現的手拿位置會影響收訊的 YouTube 影片:
或許大家都大驚小怪了?
