Letter from Apple Regarding iPhone 4

Dear iPhone 4 Users,

The iPhone 4 has been the most successful product launch in Apple’s history. It has been judged by reviewers around the world to be the best smartphone ever, and users have told us that they love it. So we were surprised when we read reports of reception problems, and we immediately began investigating them. Here is what we have learned.

To start with, gripping almost any mobile phone in certain ways will reduce its reception by 1 or more bars. This is true of iPhone 4, iPhone 3GS, as well as many Droid, Nokia and RIM phones. But some users have reported that iPhone 4 can drop 4 or 5 bars when tightly held in a way which covers the black strip in the lower left corner of the metal band. This is a far bigger drop than normal, and as a result some have accused the iPhone 4 of having a faulty antenna design.

At the same time, we continue to read articles and receive hundreds of emails from users saying that iPhone 4 reception is better than the iPhone 3GS. They are delighted. This matches our own experience and testing. What can explain all of this?

We have discovered the cause of this dramatic drop in bars, and it is both simple and surprising.

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.

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.

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.

We have gone back to our labs and retested everything, and the results are the same— the iPhone 4’s wireless performance is the best we have ever shipped. For the vast majority of users who have not been troubled by this issue, this software update will only make your bars more accurate. For those who have had concerns, we apologize for any anxiety we may have caused.

As a reminder, if you are not fully satisfied, you can return your undamaged iPhone to any Apple Retail Store or the online Apple Store within 30 days of purchase for a full refund.

We hope you love the iPhone 4 as much as we do.

Thank you for your patience and support.

重點翻譯：
Apple知道iPhone 4的收訊問題後很驚訝，因為Apple認為iPhone 4是他們推出最好的產品。在手機收訊方面，無論是iPhone 4 iPhone 3GS Nokia或RIM或其他廠牌的任何手機，用手握住手機都會造成訊號少幅下跌，約是一格到兩格。但iPhone 4的一些使用者表示當手握住iPhone 4，它會不正常的大量減少訊號。Apple感到相當意外並展開調查。

同時間，Apple也收到了數以百計的消費者的email，告知iPhone 4的收訊確實比iPhone 3GS好。而這也與Apple的測試與預期相符。於是Apple要找出為甚麼同時間有兩種感受？

Apple發現他們的手機訊號計算公式完全錯誤，因此它們請教了AT&T，也得到了一個新的公式。許多使用者誤會當緊握iPhone 4會從滿格到斷訊，其實他們處在的地點本身收訊就已經不好，應該只有兩三格，但iPhone 4卻顯示滿格。於是讓消費者產生誤會。其實緊握的iPhone4 只是從2格變成無訊號。而非不正常的從滿格變成無訊號。Apple將會修正訊號公式，並提供所有消費者更新。因為這個錯誤從第一代iPhone就存在，因此這個更新將包含3GS與3G的版本。

Apple重新測試了所有的東西，還是得到相同的結論，iPhone 4是他們所賣出收訊功能最好的產品。優於3GS 3G


同時，只要你不是完全滿意，30天內，Apple接受所有未損傷的iPhone進行全額退貨。

====================================
這個聲明跟台灣目前手上有iPhone4 的人測試大致符合

1.在訊號密集或穩定處如戶外，不管手怎麼緊握iPhone 4的訊號都不會減少
2.在一些收訊較差的室內，有些手機僅顯示一到兩格，但iPhone仍有滿格或四格。這時候用手一握就變成零格或無訊號
3.許多使用者反應，iPhone 3GS也有相同的訊號減弱問題。因此有可能是韌體所造成的錯誤。

如果是這樣真的就太好了哈哈
相信那些說比3GS收訊好的是對的

同時，只要你有一點點不滿意，30天內，Apple接受所有未損傷的iPhone進行全額退貨。

這方案會虧大= =?!

不會的,因為有很多人還排隊等著要買呢!

要買的信心大增了


ps.巴西你為什麼會輸了呢~

[a22614033]

我信心大增了..拜託台灣趕快上市..我的2G已經壞了..

希望買氣減退一些...早點在台灣上市吧~

ps....原來假摔+拉人是王道

As a reminder, if you are not fully satisfied…

這句話的意思比較接近"如果你不是完全滿意"。

不完全滿意和一點點不滿意，我想是很不同的。不過，在美國，退貨當然會比較簡單一些，但是難道就不用10%的restocking fee?

[jack8609]

某些方面來看，真的很多企業應該要多學習...
承認錯誤(也許這不是真正的問題點!?)...
但是退機全額退費...我個人覺得讓人有種 就甘心 的感覺...XD

看解釋吧
你不是完全滿意
你有一點點不滿意

完全滿意=100分
不是完全滿意=98分
只要有一點點不滿意=扣兩分=98分
這是預設你是完全滿意的狀況


或著解釋成
你不是完全滿意 (還是滿意)
你有一點點不滿意(不滿意，但只有一點點可接受)
這是預設你對iPhone 4是中立的情況

這樣解釋確實不太一樣，未必免誤會，我還是更改一下翻譯(雖然我覺得從語意上知道我在表達甚麼)


美國退貨應該不需要費用
