美苹果官网发布致iPhone 4用户公开信

    泡泡网iPhone频道7月5日 针对近期苹果iPhone 4手机爆出的信号问题，苹果近日做出了官方解释。在苹果美国官网上，发布了一封致iPhone 4用户的公开信，信里强调了iPhone 4的设计并没有问题，信号减弱只是计算信号的方法不同。不过，信中也称，如果用户仍对iPhone 4不满意，那么可以在购机30天内将手机归还给苹果，苹果将全额退款。

    这封公开信原文如下：

    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.

    以下为苹果致iPhone 4用户公开信的译文

    苹果致iPhone 4用户的公开信

    亲爱的iPhone 4用户： 　　

    iPhone 4是迄今为止苹果推出的最成功的一款产品，全世界的评论家们也都认为iPhone 4是最优秀的智能手机，而用户也十分喜欢这款产品。因此，当我们接到iPhone 4问题报告时，感到非常意外，并立即展开调查，以下就是我们的调查结果。 　　

    首先要说明一下，紧握任何一部手机都会导致信号强度下降1格或更多，iPhone 4也不例外。不仅iPhone 4，iPhone 3GS、摩托罗拉Droid、诺基亚和RIM的智能手机同样如此。 　　

    但有用户反映，iPhone 4最多时可下降4格或5格，这明显高于一般水平，因此，有人认为是iPhone 4天线设计有问题。 　　

    与此同时，我们也收到数百名用户的电子邮件，称他们的iPhone 4接收效果要好于iPhone 3GS，他们很满意。为什么会出现两种截然相反的现象呢？ 　　

    经调查后发现，导致信号减弱的原因很简单，但却有些令人意外。我们发现，用来计算应该显示几格信号的公式出现问题，在很多情况下，手机所显示的信号强度要比实际多出2格。 　　

    例如，当手机显示4格信号时，而实际上只有2格的强度。因此，有些用户所说的用手握紧后信号强度会下降好几格应该是在信号十分弱的地区，而此时手机却错误地显示4格或5格信号。 　　

    为解决该问题，我们将采用AT&T最新推荐的信号强度计算公式。真正的信号强度不变，而iPhone所显示的信号强度更加准确。此外，代表iPhone信号强度的1格、2格和3格的图标的高度也将有所增加，以便于用户查看。 　　

    在未来几周内，我们将发布一款免费的软件更新。由于该问题从一代iPhone起就已经存在，因此，该软件更新同时还向iPhone 3GS和iPhone 3G手机提供。 　　

    经过实验室的反复论证，iPhone 4的无线性能是所有iPhone手机中最好的。对于绝大部分用户而言，他们都不受该问题影响。而此次即将推出的软件更新也只是让iPhone的信号强度显示得更准确。对于因该问题而给用户带来的困扰，我们表示歉意。 　　

    如果用户仍不满意，可以在购机后30天内，将未损坏的iPhone 4退回任何一家苹果专卖店或网上商店，我们将全额退款。 　　

    最后，我们希望大家能和我们一样喜欢iPhone 4。

    泡泡网iPhone频道评论：

    首先，在这封信里，苹果仍然坚持iPhone 4的信号并不是硬件问题，而是在信号的计算和显示上考虑不到位，并说苹果官方将在近期推出一款更新解决来这一问题。

    我们且不说iPhone 4的信号到底是软件问题还是硬件问题，只是，当大部分用户都反应某款产品在使用过程中出现不便时，作为一款大公司，苹果的反应还是慢了些。■
