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.

水果GJ，我整个人都 看的人也许不会多……但没关系！
官方的，那肯定不是假的……太给力了哇！ 这要看别人的肥胖标准是怎么定的了。 Don\'t ask what the iPhone can do for you
Ask what you can do for the iPhone

-_, 那那个说打电话就会掉线怎么解释口牙？？
别那啥了，7月上市的送bumper才是正道。

话说间接的30天免费试用挺好的？？ perception, perception, perception... 记得有图标的
-91 以上的都是5格
但一旦下降20db 到-111 左右
就直接没信号了
4、3、2 这些间隔太小了
但APPLE 修改这些算法有啥用
从3格到0 和5格到0
感官差别大？
水果在降低用户心理期望
话说那屏幕变黄跟耳朵挂断电话那更严重的问题就没人关注了嘛 本帖最后由 cipher-lee 于 2010-7-3 01:54 编辑
我们已经发现了信号格显著下降的原因，非常简单却又令人惊讶。
通过调查，我们吃惊地发现，我们用来计算应当显示几格信号的公式是完全错误的。我们的公式在部分情况下，会比正常的信号量多显示2 格甚至更多。
我们已经回到我们的实验室，重新测试了所有情况，而结果都是一样的——iPhone 4的无线性能是我们所有产品中最棒的。
