Apple官方終於承認了iPhone 4 的收訊問題，不過官方的解釋鐵定跟大家想的不一樣就是...
Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength. For example, we sometimes display 4 bars when we should be displaying as few as 2 bars. Users observing a drop of several bars when they grip their iPhone in a certain way are most likely in an area with very weak signal strength, but they don't know it because we are erroneously displaying 4 or 5 bars. Their big drop in bars is because their high bars were never real in the first place.
經過調查後，我們震驚地發現我們用於計算使用多少格數顯示信號強度的公式完全地錯誤。在許多情況下，我們的公式比實際信號強度多出了兩格信號。舉個例子，當顯示四格信號時其實因該為兩格。使用者在以特定的方法握住iPhone使信號減少數格時，很有可能是在信號非常微弱的地區。但是因為錯誤的顯示四或五格信號，導致用戶無法察覺此事。
To fix this, we are adopting AT&T's recently recommended formula for calculating how many bars to display for a given signal strength. The real signal strength remains the same, but the iPhone's bars will report it far more accurately, providing users a much better indication of the reception they will get in a given area. We are also making bars 1, 2 and 3 a bit taller so they will be easier to see.
為了解決此問題，我們採用AT&T最近建議的公式來計算顯示信號強度的格數。實際信號強度維持不變，但是iPhone的信號格將會顯示的更為精確，以提供使用者對該地區信號強度更好的指標。我們同時也會使第一、第二與第三格的格子更高一點，使它們更容易閱讀。
We will issue a free software update within a few weeks that incorporates the corrected formula. Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G.
我們會在數週內發佈免費的軟體更新來修正公式。此錯誤從初代iPhone以來便一直存在，此軟體更新將同時適用於iPhone 3GS與iPhone 3G。
雖然信號格數的計算方式已經多次被討論過，實際上也真的有問題，不過也無法完全解釋對於「特定握法」造成電話斷線與資料傳輸速度下降的問題。
另外，Apple到現在還是打死不承認天線設計有缺陷就是了...
如果真的不滿意iPhone4，Apple提供購買日起30天內全額退還的服務。
